Curare, a muscle relaxant, and quinine, used to treat malaria, are just two of these medicines. 3. Predation is a type of interaction where one species preys on, or eats, another species. All these organisms are distributed over space and time, and each ecosystem and season has its unique soil community. However, if they were to be cramped, then this would cause competition, affecting the population of the species as well as others. However, many plants survive and some have even evolved to do better when fed on by other species. Is there a theory for what would happen to all the living things? Tide pools contain seaweed, a kind of algae, which uses photosynthesis to create food. Question 2. Some grasses are able to grow in the cold, dry climate.
