I apologize for the confusion. The correct answer is "A. an individual plant that lives in the ecosystem." A population refers to a group of individuals of the same species living in the same area. In this case, an individual plant within the pond ecosystem would represent a population.

I apologize for the confusion. You are correct, and I apologize for providing an incorrect response. The correct answer is indeed "C. all the algae of the same species in the ecosystem." A population within an ecosystem refers to a group of organisms of the same species living in the same area. In the given options, the algae of the same species represent a population within the pond ecosystem. Thank you for pointing out the error and I apologize for any confusion caused.
