Ticks and fleas rely on animals as a home, food, shelter and a place to reproduce.
nitrogen is the main nutrient for plants without it plants cant survive without plants herbivorous animals cant survive without them carnivorous animals cant survive without either of them omnivorous animals cant survive
plants produce oxygen which animals need.
Because plants don't have a need for animals, but animals need company and a mate so that they can continue and make their species last.
no they have a backbone without one they cant eat animals with backbones
Because animals are just like humans. They can only go without water for a few days, then if they don't get water soon they will dehydrate.
They can't live in a closed container because there is no oxygen.
Because that's how sexual reproduction works. Both egg and sperm are needed to create offspring.
Most aquatic animals cant live without bubbles, so my guess is no.
Reproduction typically occurs within specialized reproductive organs in organisms. In animals, reproduction often takes place in the reproductive tract, such as the uterus or fallopian tubes in females and the testes in males. In plants, reproduction can occur within flowers where pollen is transferred between male and female reproductive organs.
