A study of a small farm in Michigan was carried out in 2004 . A variety of organisms were found to live there, including meadow voles, grasshoppers, spiders, birds, and mice. The farmer retired and moved away, leaving the land to grow wild. The meadow voles, grasshoppers, spiders, mice, and other organisms, along with the soil, minerals, and water make up a(n) (A) ecosystem (B) population (C) community (D) food chain (E) desert biome

Key Concepts

Ecosystem

An ecosystem refers to a community of living organisms interacting with one another and with their physical environment. It includes both biotic factors (such as plants, animals, and microorganisms) and abiotic factors (like soil, water, and climate) that influence the functioning of the system as a whole.

Population

A population is a group of individuals of the same species that live in a specific area and interact with one another. This concept focuses on the dynamics within that single species, such as growth, density, and genetic composition.

Community

A community in ecology represents all the populations of different species that live and interact in a given area. It emphasizes the variety of organisms and species interactions, including competition, predation, and symbiosis, that shape the structure of the area.

Food Chain

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. It outlines the direct feeding relationships in an ecosystem, showing how energy is transferred from primary producers to various levels of consumers.

Biome

A biome is a large-scale ecological classification based on climate conditions, vegetation, and animal life. It extends over broad geographic areas and encompasses many ecosystems that share similar climatic and biological characteristics.
