Answers
Answer:
1) Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem.
2) the regions of the surface and atmosphere of the earth or another planet occupied by living organisms, this surface is known as biosphere
3) lithosphere is the rigid outer part of the earth, consisting of the crust and upper mantle, the water on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds is know is hydrosphere, atmosphere is a layer of gas or layers of gases that envelope a planet or other material body
4) a biological community of interacting organisms and their physical environment.
5) The surroundings made by humans to provide facilities to satisfy human needs is known as human made environment
6) humans depend on plants and trees for Food, oxygen and shade
(please look for images on ur textbook for 7th one)
8) Crust is the uppermost layer of earth, mantle is the second layer of earth and core is the innermost layer of earth.
9) Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.

11) iron, manganese, selenium and calcium are some important minerals for humans
