Why do animals need plants?

Plants need carbon dioxide from animals and animals need oxygen from plants

animals do, but plants don't. plants need CO2

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.

Animals need to eat plants and some plants need animals to keep them alive. [worms] [some animals eat plants]

Plants and animals need different things because they have different needs. Plants need sunlight because they make their own food and animals need plants.

plants need animals to live because we exhale carbon which plants need to complete photosynthesis.

Plants make the products animals need and animals make the products plants need.

Plants need carbon dioxide to grow. People and animals produce the most carbon dioxide. Plants need animals to live. Animals need plants to live.

plants need soil and animals need food

Plants and animals are very dependent on each other. Plants provide the necessary food that animals need, while animals supply the reactants of photosynthesis that plants need.

Of course! Animals are used for meat, which is good, and you need plants for oxygen and food.

Ah Dur! Animals that need plants to survive are called herbivores.

OF COURSE ANIMALS NEED TO EATEAT PLANTS ARE THEY WON'T GROW ARE BE STRONG ARE BE ABLE TO LIVE WITH OUT PLANTS

They need Co2 from animals. Which is why we need them, for oxygen.

Plants produce oxygen that animals need to breath and animals eat plants.

Animals need the chemical energy of the plants themselves to survive. Animals have centrioles to form spindle fibers during prophase. The centriole plants don't need it. Animals need to eat organic food but plants do not because these are capable of synthesizing their own food.

Plants obviously need soil to grow and animals doesn't need soil, they need food and water

The animals need the oxygen that plants release.

Plants and animals effect the ecosystems they live in because they depend on each other for survival. Plants produce oxygen which animals need to breath. Animals also need plants for food. Animals release carbon dioxide from breathing which is what the plants need to make the oxygen. Animals help fertilize the ground for the plants with their feces.

well plants ned animals and animals need plants. like:when i animals die.it fertilzie the grown or the dirt and a plant grown there.if that did not happen then it would a ltiilt harder for plants to grow and how animals need plaints.FOOD....

the plants need the animal's carbon dioxide and animals need the plants' oxygen .

Well, plants need carbon dioxide and animals need oxygen.

Plants need sunlight to conduct photosynthesis.

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

plants need to photosynthesis as this is how they make their food. animals do not as they get their food from other sources such as plants and other animals.
