The Living World

Ecosystem Structure

• Biological Populations and Communities:What's the difference? A population is made up of one specific species, whereas a community is multiple types of species(or multiple populations) all put together.
• Ecological Niche:The role an organism plays in an ecosystem based on it's abilities and where it lives.

Species Interaction

•  Keystone Species:A species that is highly important to an ecosystem, if it were taken out of the ecosystem everything would be effected. 

 

Biomes

 

 

 

 Energy Flow

• Photosynthesis:The process of plants using sunlight to synthesize foods from water and carbon dioxide.

Ecosystem Diversity

• Biodiversity:The variety of living species in an ecosystem.
• Natural Selection:The idea of organisms who are better adapted to their habitat survive longer and reproduce more.
• Evolution:The process of something developing.
• Ecosystem Services:Components in nature that people value.
