communication between cells
not for long because an animal neds the digestive system to provide essential amino acids and essential vitamins and minearals which said animal could not live without
Foods from animal sources provide complete proteins, which contain all essential amino acids needed by the body.
Yes, many animal species are dependent on plants for food, either by directly consuming plants or by eating animals that have consumed plants. Plants provide essential nutrients and energy for many animal species, making them a crucial part of the food chain.
because the energy comes from the sun, plants absorb energy, an animal eats the plant and then we eat the animal. The animal didn't create the energy.
yes it does use animal testing because it is medicine.

Animal life depends on plants in two ways. Plants provide food for many animals and also, the plants provide oxygen for animals
The trees provide fruit because the seeds will not be digested and the animal`s dung will be fertiliser.
Yes but only to animal life ,because it helps scavengers get food some times
because man provide his basic want and need
No, because zoos provide them with there needs.
Its because the plant needs to be stable because it would be really floppy, and the animal cell does not because it can move around the animal and it does not need to be stablised. Animal cells do not have chlorophyll because they don't need it. Plant cells need them because they take in sunlight and turn it into a sugar that is used for food for energy. Animal cells do not get their energy from the sun directly, they get it from oxygen. Animal cells do not photosythesise, which is what chlorophyll is for.
