That would be oxygen.
Yes but some animals dont eat plants cause they are carnivores stupid.
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.
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.

The animals need the oxygen that plants release.
plants need soil and animals need food
because they use plants and animals to make fossil fuels
no they dont
people................. or plants
No, because man and animals produce carbon dioxide and plants needs carbon dioxide.
Of course! Animals are used for meat, which is good, and you need plants for oxygen and food.
Plants and animals need different things because they have different needs. Plants need sunlight because they make their own food and animals need plants.
They need Co2 from animals. Which is why we need them, for oxygen.
