Green plants are the first living organism in a food chain. where do plants get the energy that they pass along to the primary consumers in their food chains? a. from secondary consumers b. from the sun c. from other plants d. from decomposersgreen plants are the first living organism in a food chain. where do plants get the energy that they pass along to the primary consumers in their food chains? a. from secondary consumers b. from the sun c. from other plants d. from decomposers

An easy way to calculate the amount of energy available at each level is to what?

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
