Affects of Abiotic Features  Temperature  Affects the type of plants >Type of food and shelter > Type of animals that can survive in the ecosystem  Animals are sensitive to temperature  Light  Sunlight warms Earth’s surface and atmosphere. Energy from sunlight supports all live on Earth. (The sun is the primary source on direct energy) Abiotic factors include both the physical and chemical parts of an ecosystem.

 Soil  An important abiotic factors in land ecosystems.
