balance between plants & animals is essential because plants are autotrophs , they can make their own food but animals are heterotrophs , they cannot prepare their own food so they have to depend on plants ( autotrophs) for their food.
moreover, to prepare their food plants need C02 , WHICH IS RELEASED IN THE ENVIRONMENT BY ANIMALS ( BY RESPIRATION) & IN TURN THEY RELEASE Oxygen which is essential for the life of animals & also to maintain balance in nature , the number of plants should be equal to the number of animals.
Interdependence between plants and animals is important as without interdependence nothing can survive. for example; plants provide animals with oxygen and animals give out carbon dioxide which is necessary for the plant to make food through photosynthesis. So, if any one of the plant or the animal kingdom dies, many other living things have to suffer. That is why interdependence of plants and animals is important.

Nitrogen is essential for living organisms because it helps plants grow, and plants supply animals their food. And without plants we would die.
Some animals eat plants. Believe it or not, some plants eat animals. It's a cruel world. Avoid it at all costs.
plants are the main food producers in a food chain and animals can get their energy from plants directly or indirectly.
Some of the essential functions that animals carry out include pollination and the provision of food for each other. Animals are at different levels of the food chain and therefore provide food for animals higher up the food chain. They move seeds from one place to another and help plants to reproduce.
Symbiotic relationships
co2 helps the plants which create oxygen which helps us
lets say cougars disappear and the deer population takes off, food for deer will be scarce because there are so many deer and no predators to keep them in balance.
Oxygen
Water is essential for metabolism .
Yes, but plants can make them themselves, animals have to get them from their food.
Nitrogen is essential for living organisms because it helps plants grow, and plants supply animals their food. And without plants we would die.
Plants and animals are fundamental to ecological balance. Plants could exist without animals but animals could not live without plants. Without animals plants would eventually stabilise to a new level of ecological equilibrium.
Oxygen.
plants makes there food by themselves but animals do not
What's the difference between eukaryote and prokaryote and animals and plants ?
Yes, but they need to be careful. The biggest problem is getting all the essential amino acids; all animals have them but not all plants. But it doesn't take much, half a can of tuna a day is plenty.
O2 in and CO2 out for animals, and the opposite for plants.
