Being so small, they can get away with using a much cruder sustem for "gas exchange", which is what the lungs do for us.
Just like humans do. they inhale to inflate their lungs and deflate to release carbon dioxide and deflate their lungs at least land animals do. sea animals use a special set of lungs called gills
we humans need oxygen but plants dont need oxygen in general.they need co2 carbon dioxide we need happiness for our mind...rest...entertaiment... money Plants dont need happiness ..rest...entertainment and money.. all plants need is light water CO2. we need sex plants dont need sex plants usually have asexual(non sexual)reproduction ...just wind ,bee,fly,will do the pollination for plants.

Because we eat animals such as cows and pigs. If they dont reproduce, the population will decrease. And then their will be no more meat to eat and we might die. The same things with plants because if both plants and animals die then we will surely die also.
They need Co2 from animals. Which is why we need them, for oxygen.
plants need your help to stay alive because they can`t get up and move around you need to take care of plants and animals
Yes but some animals dont eat plants cause they are carnivores stupid.
because they don't breath like humans

animals need plants because animals like deer depend on plants like grass(to eat). and plants need animals because if the animals did not eat the plants then the plants would become an invasive species. and then it would be hard to take back, or exterminate the plant.

Plants wont grow because they dont have any water.. & animals need plants to eat or they will die.. If animals die then we will be hungry because we cant eat them... Etc

Humans need oxygen to survive and think.If you dont have enoff oxygen for your brain it will stop working and you will eventually die.Humans also need oxygen sso that they can breath out carbon dioxide.If we didnt have oxygen we wouldnt have carbon dioxide.Carbon Dioxide is the thing that plants breath in.So if we didnt have oxygen plants would die.And then the animals that eat plants will die.Then the animals that eaet does animals will die.And we are omnivore(means we eat plants and animals)so if there were no plants and animals we will die of hunger That is why we need oxygen Patronum483 :)
Lungs do not differ that much in domestic animals. These animals need oxygen just like the animals that are in the wild.
plants need soil and animals need food
The animals need the oxygen that plants release.
No, because man and animals produce carbon dioxide and plants needs carbon dioxide.
