1. What are the biotic factors of an ecosystem?

2. What are the abiotic factors of an ecosystem?

3. In what ways does one biotic factor interact with the abiotic factors?

4. Pick one biotic factor, if you were to change it dramatically somehow, how will this change affect the ecosystem?

5. Pick one abiotic factor, if you change it dramatically somehow, how will this change affect the aquarium?

1) Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.

2) Abiotic factors are the nonliving physical and chemical components of an ecosystem, while biotic factors are the living components of an ecosystem. Both types of factors affect reproduction and survival.

3) Water is abioitic and is needed by every living organism

Soil is abioitic and is needed by plants

Trees and other plants release water vapor from their leaves (a process called transpiration) that create humidity (which in turn influences how much rain falls in an area)

The climate in an area influences the special adaptations that plants and animals have. For example: warm fur coats and thick layers of fat to keep warm in cold climates, animals in dry, hot climates (desert) have large ears to release heat and cool down.

Biotic factors also influence abiotic factors.

Animals produce waste (go to the bathroom) which in turn will become nutrients in the soil.

4) Plants because I can change oxygen level and affect other biotic factors by cutting off plant eating animals food supply.

5) decrease heat will affect biotic factors, like animals, warmth.
