Climate change as well as other human-driven environmental changes continue to cause loss of biodiversity in the coming decades in addition to high rates of species extinctions. Biodiversity is a term that can be used to describe biological diversity at a variety of different scales, but for now let's consider species diversity. Each rectangle represents a plant community containing individuals of various species indicated by color and the total number of individuals corresponds to the productivity of the ecosystem. Based on trends illustrated by the images, what conclusions apply? Choose ALL that are appropriate.
A) While species may fluctuate, biomass remains constant. B) The green species increases in abundance during warm years. C) The productivity of the ecosystem decreases as the climate changes. D) Invasive species, represented by red, move in and displace native species. E) Decrease in one species is compensated for by an increase in another species.
