Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.

Biodiversity is not distributed evenly on Earth, and is richest in the tropics. These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species. Marine biodiversity is usually highest along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future.

Rapid environmental changes typically cause mass extinctions. More than 99.9 percent of all species that ever lived on Earth, amounting to over five billion species, are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon). In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Earth.

An omnivore is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet.

This live-action video program is about the term omnivore. The program is designed to reinforce and support a student's comprehension and retention of the term omnivore through use of video footage, photographs, diagrams and colorful, animated graphics and labels.

Viewers will see and hear the term omnivore used in a variety of contexts providing students with a model for how to appropriately use the word. Related words are also used and reinforced with visuals and text.

Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms (Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). What this means is that physical characteristics are often not reliable indicators of whether an animal has the ability to obtain energy and nutrients from both plant and animal matter. Owing to the wide range of entirely unrelated organisms independently evolving the capability to obtain energy and nutrients from both plant and animal materials, no generalizations about the anatomical features of all omnivores can realistically be made.

The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. Frugivores include maned wolves and orangutans; insectivores include swallows and pink fairy armadillos; granivores include large ground finches and mice.

All of these animals are omnivores, yet still fall into special niches in terms of feeding behavior and preferred foods. Being omnivores gives these animals more food security in stressful times or makes possible living in less consistent environments.

Educational video for children that talks about terrestrial and aquatic habitats. A habitat is a place that has the necessary resources for living beings to survive. These resources are light, water, temperature, soil and oxygen. The different characteristics of these resources are what make for different habitats. There are two types of natural habitats: terrestrial and aquatic. Among terrestrial habitats there are deserts, jungles, forests, grasslands and savannas. Aquatic habitats include landscapes such as rivers and lakes, oceans and seas. In aquatic habitats, living things have adapted to living in water.

What are you waiting for? Did you now that the fastest bird is the peregrine hawk? This bird of prey can reach up to 400 kilometers per hour whist free falling. Wow it’s so fast, poor dove if it were to cross its path…

On the other hand, the American Woodcock is the slowest bird on the planet, flying at a mere speed of 8 km per hour. Oh, check out
it´s cute little babies!

And did you know that the fastest land bird is the ostrich? This huge bird, actually the largest in the world, cannot fly but can reach up to 70 kilometers per hour…running…it’s faster than a moped!
This tiny hummingbird also holds an impressive record. Besides being the smallest bird, it can also flap its wings 200 times per second or in other words, 12 thousand times in a minute…incredible! They beat so fast that you can hardly even see them, and it looks like they are floating in the air whilst eating…

Did you know that the penguin is the aquatic bird champion? Penguins don’t fly and on land are rather clumsy, but they are incredible in the water. Some species can reach the speed of…36 kilometers per hour. They swim four times faster than a person can…but the most impressive penguin is the emperor penguin. A person can dive to the depth of 260 meters whereas this penguin species dives 535 meters deep and can hold its breath for 5 to 18 minutes. It’s a bird, it has a beak and feathers but it seems as if it wants to be a fish…

Now we have learnt a few records and fascinating facts about birds. The truth is it is beautiful observing them fly in the sky or swim in the sea but as we are always reminding you in Happy Learning, so as to continue enjoying them, we must look after our environment; do not contaminate the air, the sky, the rivers and seas. We must take care of our nature and all that is around us, and like that we will be able to live in a happier world.

What are you waiting for? The dolphin, a very friendly mammal

Hello friends, and welcome to a new Happy Learning video. Today we are going to learn about one of the most friendly and fun mammals, presenting the dolphin.

Dolphins are aquatic mammals which live in most seas around the world.

Dolphins have a dorsal fin on the top part of their body and two lateral fins as well as a flat tail called a fluke, which they use to beat the water in an up and down motion, allowing them to swim at great speeds as well as completing agile jumps out of the water.

Did you know that dolphins don't have a nose? They have a beak and they breathe through a hole above their head. Can you see it? well this hole is called the blow hole and they close it every time they go under water so as not to let water come into their lungs.

Dolphins can submerge themselves up to 300 meters deep and can hold their breath for almost 25 minutes!

Do you know how dolphins sleep? It is really curious...because they sleep...in sections. First half of their brain and half of their body goes to sleep and when that part wakes up, the other half goes to sleep. It is for this reason that they sleep with one eye open, always aware of what is going on around them. Like this they are always alert...

Dolphins belong to the cetaceous family, like whales.
The average length of a dolphin is around 4 and a half meters, which is the length of normal car and they weigh about 300 kilos.

For orientation, dolphins use a system called echolocation. The sounds the dolphins emit travels through water until it rebounds off an object found in its path, and sends it back to the dolphin. Now the dolphins can calculate how far away the object is, its size and also its shape.

Dolphins are carnivorous, their main source of food is based on crustaceans, fish, squid and octopus.

Dolphins just like all mammals are viviparous and the gestation of a baby takes 12 months. During the first month of a baby´s life, it feeds on the mother's milk and then the baby is taught how to hunt by other members of its family.
Dolphins are not scared of humans and when they encounter them, they are very friendly. They are really playful and curious animals.
Dolphins tend to live in a group and are extremely intelligent. As they are together in a group they help each other by defending off sharks and orcas by butting them with their strong beak.

But do you know what the dolphin´s biggest problem is? The humans. It is because of humans hunting them and contaminating the waters which is causing many dolphins to die. Many dolphins have been trapped in fishermen's nets or suffocated with plastic bags and rubbish which has been thrown in the sea, but this is a problem happening not just for dolphins but for many other marine species, such as turtles and seals. It is for this reason that it is just so important to look after our seas and oceans and that we should never, ever, ever, throw anything into the water.

If we maintain nature clean, dolphins as well as all other living creatures will be very happy.

So goodbye for now and don't forget to subscribe to Happy Learning.
