Ascientist is studying the biodiversity of an ecosystem that has a cool climate. the scientist counts the number and types of organisms in a 5 foot by 5 foot area. she finds that the ecosystem has very low biodiversity. another scientist studies the same ecosystem. he counts the number and types of organisms in a 1,000 foot by 1,000 foot area and finds that the ecosystem has high biodiversity.

what likely caused these different results?

a. the scientist who found high biodiversity observed fewer niches.

b. the scientist who found high biodiversity observed more plants than animals.

c. the scientist who found low biodiversity studied the ecosystem on cold days.

d. the scientist who found low biodiversity studied too small of an area.
