6.12 C Ecosystem and Organization

What is the simplest level in an ecosystem?

• Single Organism

• A community

• A cell

• Population

2. How do the organisms inside of a population interact with each other? 

• 1. reproducing offspring and living together

• 1. playing games and designing habitats

• 1. competition with others until there is only one

• 1. Predator Prey Relationship

What makes up the African grassland ecosystem?

• Communities of interactions between gazelles, zebras, lions, and other living organisms.

• Only nonliving things like air, soil and water.

• Single organisms that have no interactions.

• Autotrophs that have many interactions.

1. What is the difference between a population and a community?

• 1. A population is a group of different species, while a community is a group of similar species.

• 1. A population is a group of the same species, while a community includes different populations.

• 1. A population is a larger group than a community.

• 1. A population can exist without a community.

In an ecosystem, what role do the abiotic factors play?

• They provide the backdrop but do not interact with the organisms.

• They are less important than the organisms.

• They interact with and support the life of organisms.

• They only provide living space for the organisms.
