Biomes are very large terrestrial ecosystems that contain various smaller but related ecosystems within them. Biomes are characterized by distinct climate, vegetation, and organisms, with examples including tropical rainforests, deserts, and grasslands. Each biome supports a unique set of species that are adapted to the specific environmental conditions found in that particular region.
A land, or terrestrial, ecosystem is all the living organisms and their physical environment on a particular piece of land. Terrestrial ecosystems may interact and overlap with marine (salt-water) and limnological (fresh-water) ecosystems. A number of terrestrial biomes can be used to classify smaller ecosystem

Sunlight is essential for photosynthesis, the process by which plants produce energy-rich organic compounds. This process provides the energy source for most terrestrial ecosystems. Sunlight also regulates temperatures and influences patterns of rainfall, which can in turn affect the types of organisms that can survive in a particular environment.

The initial food source for most terrestrial ecosystems is typically plants. Plants produce their own food through photosynthesis, which forms the base of the food chain for animals and other organisms in the ecosystem.
Two organisms that are commonly at the top of the food web are apex predators such as lions in terrestrial ecosystems and great white sharks in marine ecosystems. These organisms have few or no natural predators and play a crucial role in regulating the populations of other organisms in their respective ecosystems.
