In a dense tropical rainforest, many small plants are observed growing high up on the branches of tall trees instead of on the dark forest floor. Identify the primary resource these plants are competing for and explain why this behavior helps them survive.

In a desert ecosystem, plants like cacti are often found growing far apart from one another. Identify the primary resource they are competing for and explain how this competition affects the ecosystem's appearance.

In a grassland ecosystem, zebras and gazelles both feed on the same species of grass. If a new herbivore that reproduces much faster is introduced and also eats that grass, explain how the competition for resources changes and describe one likely impact on the zebra population.
