What is an example of a keystone species in a food web? How do mutualism and parasitism compare? What are some decomposers in a marine food web? What is a decomposer's role in an ecosystem? What is symbiosis in ecology? What is the bottom of the ocean food chain?
解析 C。解析:文中提到“When certain species disappear, it can disrupt the balance of these ecosystems. For instance, if a keystone species is lost, it can have a domino effect on other species and the overall functioning of the ecosystem.”,所以关键物种的消失会导致生态系统的破坏。

Later experiments convinced him that Pisaster ochraceus is a "keystone species," a creature who exerts disproportionate influence over its environment. Eliminate the keystone and the whole system gets disheveled. The Verdict: Apex predators don't just affect the animals that they hunt. Removing a ...
An umbrella species is chosen for its specific characteristics (for example, its large size) to protect other species in the same ecosystem during conservation efforts. What's the difference between umbrella species and keystone species? Umbrella species is chosen as a representative of an ecosystem...

Species diversity is the number of different species that are represented in a given community. The effective number of species refers to the number of equally
Fire also changes how nutrients flow throughout longleaf ecosystems, in ways we are just beginning to understand. For example, researchers have discovered that frequent fires provide extra calcium, which is critical for egg production, to endangered red-cockaded woodpeckers. Frances James, a retired...
What is an example of biodiversity?Biodiversity:In ecology, biodiversity is broadly defined as the range and variation of life in an ecosystem. This can include over a within a region, between regions, and over a period of time. Additionally, different measures of biodiversity include genetic ...
