Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.
Answer:
A lot...
Explanation:
Having abundant species in an ecosystem (plant or animal) the benefit one another is called <em>biodiversity. </em>Biodiversity can consist of the mere food chain, to complex symbiotic relationships among creatures. If an ecosystem were to have no species, there would be no balance between a self-sustaining ecosystem. Any naturally found ecosystem will have biodiversity, otherwise that ecosystem will break (usually it's brand new, crashing ecosystems have to have even one factor removed to do so. Therefore, why would this said 'ecosystem' even begin?).

Organisms compete for the resources they need to survive- air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).
