How do different species of animals and plants interact?

Different species of animals interact by: warning each other when a threat may come close, the message animals send out may not be meant for other species but they will pick up on it. Animals from different species also need each other. Predators need small, less skilled animals so that they may feed themselves and/or their families that night. The smaller animals need the predators, as much as they wish that they weren't there. If there was no predators then the population of that species would rocket up and make it harder for the animals already there to live.

Different plants need each other because when one plant dies, it decomposes. The decomposing plant creates more fertile land for plants around it to feed off. So the weaker plant that may get beaten to the sun by other plant dies and fuels its enemies so that they may fight off other plants and grow.

Even animals and plants need each other! If animals weren't around then plants wouldn't get eaten and thinned down therefore wouldn't be encouraged to grow more. Humans are animals, and we encourage the growth of plants and rely on them for most of our foods. Bees for example spread pollen and help flowers grow, with out bees flowers would die. Plants create oxygen with all land dwelling animals rely on to live.

The Living things all help each other, even with out noticing it. If animals didn't exist plants wouldn't be able to survive and would loose the need to create oxygen because the world would already have too much making air thick with oxygen and making it harder for plants to breathe as well because there would be no carbon dioxide for them to breathe in.

Every living thing needs every other living thing in order to survive.
