If all the plants on earth died, so would the people. When green plants make food, they give off oxygen. This is a gas that all animals must breathe in order to stay alive. Without plants, animals would have no oxygen to breathe and would die.

If there were no plants on the planet we wouldn’t be able to breathe. Humans in particular, however, also produce other waste. Modern life produces considerable volumes of chemical waste in all kinds of ways. Factories, cars and heating, for instance, but modern building materials and fabrics also ´breathe´ out toxins.

Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.

Trees andplants give out oxygen, if we wouldcut them all, Populationwill not stop increasing, but oxygen will reduce. Withouttrees and plants, humans as well animals would not be able to survive, sincethe air would be not suitable to survive on the planet.

There are no trees There are four countries with no forest whatsoever, according to the World Bank’s definition: San Marino, Qatar, Greenland and Oman.

Do trees sleep when the sun goes down? According to research, while trees may not sleep in the same way animals do, they do relax their branches during nighttime, which suggests that yes, trees have activity-rest cycles. These cycles can also vary depending on the tree species.

Do plants feel pain? Short answer: no. Plants have no brain or central nervous system, which means they can’t feel anything.

Trees can have either male or female parts. In addition, there are also trees that do not contain any flowers at all, making it even harder to figure out the tree’s gender. Dioecious Trees. If a tree is dioecious it only has male or female parts, not both.

These five animals never sleep:

• Jellyfish.
• Bullfrogs.
• Insects (multiple)
• Sea Urchins.
• Baby Dolphins.

That’s because the kangaroo rat can go literally its entire life without once drinking water.

The answer to “If I drink I die, if I eat I live. What am I?” is fire.

Answer: Kangaroo rat The tiny kangaroo rat located in the south-western deserts of the United States does not drink water for its whole lifespan.

Squids have three hearts; one main heart and two branchial hearts. Octopuses and squid have three hearts. Earthworms have five hearts. Scientists are studying cockroach and hagfish hearts to help design solutions for human heart disease.

Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood. Their body cavity has no lining or fluid within it. They obtain nutrients and oxygen directly from the water that they live in.

skinks

Brachiopods have black blood. Octopuses have a copper-based blood called hemocyanin that can absorb all colors except blue, which it reflects, hence making the octopus’ blood appear blue.

Explanation: Currently, there is no animal with that amount of hearts. But Barosaurus was a huge dinosaur which needed 8 hearts to circulate blood upto it’s head. Now, the maximum number of hearts is 3 and they belong to the Octopus.

Sponges

Jellyfish don’t have brains They don’t have a heart, lungs or a brain either! So how does a jellyfish live without these vital organs?

Black Rhinoceros (Diceros bicornis) This dilute milk may have something to do with the animals’ slow reproductive cycle. Black rhinoceroses become capable of reproducing only once they reach four to five years old.

octopuses

Octopuses have 9 brains because, in addition to the central brain, each of 8 arms has a mini-brain that allows it to act independently. Octopuses have blue blood because they have adapted to cold, low oxygen water by using hemocyanin, a copper rich protein.

A human heart has four chambers, each with a specific job—if any of them fail, it’s bad news. A cockroach heart, on the other hand, has 12 to 13 chambers, all arranged in a row and powered by a separate set of muscles.
