Ecosystems and AdaptationsLesson 6.1 – Organization of the Biosphere

I can describe the levels of organization in the biosphere. I can identify biotic and abiotic factors in an ecosystem. (3e)

1. All organisms live in and depend on their environment.

a. The scene you described above would be considered your environment.

2. The parts of the Earth that contain living things are together called the biosphere.

a. All land and water as well as the lowest part of the atmosphere are part of the biosphere because living things are found in all of these places.

I can describe the levels of organization in the biosphere. I can identify biotic and abiotic factors in an ecosystem. (3e)

3. The biosphere is divided into smaller parts called ecosystems.

a. Ecosystems include all the living and nonliving parts of a certain environment.

i. The living parts are called the biotic factors.

1. In a pond, the biotic factors would be frogs, fish, plants, algae, etc.2. Animal remains (dead animals) and animal waste (poop) are considered to be biotic.

I can describe the levels of organization in the biosphere. I can identify biotic and abiotic factors in an ecosystem. (3e)

ii. The nonliving parts are called the abiotic factors.

1. In the pond example, the abiotic factors would be the light, temperature, weather, soil and water.

iii. Remember, “bio” means life and “a” means without.

I can describe the levels of organization in the biosphere. I can identify biotic and abiotic factors in an ecosystem. (3e)

4. Each ecosystem contains different habitats which are the places that different organisms live.

a. A habitat provides all the biotic and abiotic factors that an organism needs to live.

I can describe the levels of organization in the biosphere. I can identify biotic and abiotic factors in an ecosystem. (3e)

5. Each organism has a specific role (job) that it does in its environment. This is referred to as its niche (“nitch” or “neesh”)

a. In the pond, mosquitos lay eggs on the surface of the water and frogs eat some of these mosquito eggs. Animals that die are broken down by fungi and bacteria.
