According to the "bottom-up" theory of how ecosystems are structured, the availability of edible plants is what primarily determines an ecosystem's characteristics since it determines how many herbivores the ecosystem can support, which in turn determines how many predators it can support. ████ ██████ ████ █████ ████ █ █████████ ██ ███ ██████ ██ █████████ ████ ████ ██████ ██████ ██ ███ ████ ██ ███ ██████████
Summarize Argument: Phenomenon-Hypothesis
The bottom-up theory claims that ecosystems are determined by how many edible plants they can support. This is because edible plants support herbivores, which in turn support predators. Everything depends on edible plants.
Notable Assumptions
While the bottom-up theory holds that the population of predators has little effect on ecosystems, the theory doesn’t account for the population of herbivores. Given that the bottom-up theory states that edible plants determine the characteristics of an ecosystem, this means the bottom-up theory assumes that an influx of herbivores also wouldn’t cause any changes. Nothing besides the availability of edible plants can have a deterministic effect on ecosystems.
