When many different species live in an environment, the environment has high (blank) . if the number of predators increase in an area, the immediate effect will be a (blank) .

When many different species live in an environment, the environment has high biodiversity. If the number of predators increase in an area, the immediate effect will be a unstable ecosystem (decrease in the population of prey.)

Explanation:

In ecology, biodiversity can be described as the different plants and animals which live in a habitat. If a habitat has many kind of different species, then the habitat or ecosystem will have a wide biodiversity. The wider the biodiversity, the more stable an ecosystem will be.

If the number of predators will increase then the ecosystem will become unstable. There will be more competition for resources.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
