They need waste, bacteria, and plants.
I think that the plant can use the animal waste as fertilizer and plants can serve as food and they give off oxygen.
Oxygen is the waste product of plants that animals need in the process of oxidative phosphorilation.
Two waste products common to plants and animals are carbon dioxide and water. However, only plants that photosynthesize in the dark have water as a waste product.
the waste has nutrients in it that help the plant
Some animals are herbivores therefore, they eat plants and the plants provide them with energy. :)
Plants help animals by providing food and animals help plants by giving off bodily waste which fertilizes them.
Plants, Animals, and Bacteria
Plants can obtain a variety of things from animals. The main things are CO2 from the exhaust of mammals, and the minerals/nutrients from animals' waste. Nitrogen from chicken waste is a very good example.
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 need chloroplasts to carry out photosynthesis. Photosynthesis gives the plants their food. In turn, many animals (herbivores) eat these plants. Some animals (carnivores) eat the animals who eat the plants. Plants hold an extremely important part in the food web.In addition to photosynthesis supplying food, it also creates oxygen as one of its waste products. Animals need this oxygen to breathe.YOUR WELCOME
Cell transport (food in, waste out) is driven by the Na+/K+ ATPase pump. Works for both plants and animals.
