Ecology

The biology of a population is greater than the collective biologies of its individuals. Multiple members of the same species in close proximity constitute a population. Different populations in proximity constitute a community, which in conjunction with its nonliving environment constitute an ecosystem. The relation of each organism to all other organisms and factors in its habitat and environment make up its ecology. This includes structure, genetics and mutations, metabolism, diversity, fitness, adaptation, climate, water, and soil condition. The conditions that constitute an organisms life cycle is its habitat. Both negative and beneficial interactions with other organisms are parts of a plant's ecology. Herbivores eat plants, but plants can also defend themselves. Some other organisms form beneficial relationships with plants, called mutualisms, for example with mycorrhizal fungi that provide nutrients, and honey bees that pollinate flowers. A biome is a large part of the earth that has very similar abiotic and biotic factors, climate, and geography, creating a typical ecosystem over that area that is characterized by its dominant plants. Examples include tundra and tropical rainforest.
