8. if you removed all the cheetahs from a large area of savanna which of the following is a direct effect that could be explained by the diagrams? a: an increase in the lion population b: increase in the gazelle population c: an increase in the grass population d: increase in the shrub population

B: increase in the gazelle population.

Explanation:

This would be the most likely consequence of removing all the cheetahs from a large area of savanna. This is because of how the food chain operates in this ecosystem. The cheetahs are considered predators in this ecosystem, and their main prey are gazelles. If the population of predators decreased, less gazelles would be hunted, which would eventually lead to an increase in the gazelle population.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
