Ecology And How Things Behave

What is an ecosystem?

• An area made of living and non living things that interact with each other.
• Often categorized by climate and condition of soil.
• In an ecosystem, each animal has its own niche, or role to play.

Scales of ecosystems (examples)

• Micro: pond, puddle, tree trunk, under a rock, etc. 
• Messo: forests or large lake 
• Biome: rain forest with all of its features

Food chains

• All living things need energy to grow and to live right?
• Describes  the way that different organisms eat each other
• Example:    grass----->zebra---->lion

Producers and consumers

• Plants are producers
• Animals are consumers

-Ivores

• Herbivores- animals that only eat plants
• Carnivore- animals that only eat other animals
• Omnivores- animals that eat both plants and other animals

Decomposers

• Bacteria and fungi are decomposers
• Eat decaying matter and dead plants
• After the decomposes decompose themselves,
• they turn into nutrients for the soil (fertilizer).
