Which ecologist showed in a long-term experiment on outdoor plots that biodiversity is of central importance to the productivity, stability, resistance to the invasion of ecosystems and fertility of their soils?

Explanation

The correct answer is David Tilman. Key Points David Tilman:- He showed in his long-term experiment on outdoor plots that biodiversity is essential to the productivity, stability, resistance to invasion of ecosystems, and fertility of their soils. His experiment involved growing different combinations of plant species and measuring the resulting productivity and stability of the ecosystem. The results showed that ecosystems with higher biodiversity were more productive and stable, and had greater resistance to invasion by non- native species. This experiment supports the idea that preserving biodiversity is crucial for maintaining healthy and functioning ecosystems. Additional Information Karl Mobius:- He was a German zoologist who studied marine ecosystems, but did not conduct research on the importance of biodiversity. Herbert Spencer:- He was a 19th-century philosopher and sociologist who did not conduct any research on ecology or biodiversity. Edward Osborne Wilson:- He is a renowned biologist who has done extensive research on biodiversity.
