Question

what would happen in a plant population if it grew in the absence of predators and competition?

Answer 1

In our environment balancing is very important for suitable ecosystem . In ecosystem producer and consumers levels always should  be kept  in balance , like population of animal and as well as population of plant and predators always take a importance role to keep balancing of plant population (predators can impact on population ).

So in absence of predators and competitions ,there is always a chance to increasing the plant population and more population of plants can impact on animals by indirectly . If there is more plant than usual , there is chance to increasing the no of animals who eat plants and the population of animals that eats that animals might also increase . By these way increasing of population than usual is not good for ecosystem as well as environments .
