What is a biotic factor
A living or once-living part of an ecosystem
Define Succession
A series of predictable events that occur over time that take place in a community. (can be a long or short period of time)
Define flow of energy
how energy is transferred from one organism to another, lowering in kJs (Kilocalories)
Define ecological organization
The organization of the trophic levels. Like primary consumers and such.
Who in our friend group can scream really loud?
Addy obviously
Whats another name for consumers and why
Heterotrophs because we consume things for energy
Whats another name for producers and why?
Autotrophs because they use sunlight to make their own food/energy
Who is practically a siren?

What are some differences between primary and secondary succession
Primary succession starts out with bare rock (no soil) and it takes thousands of years to get to a climax community with the help of pioneer species that only primary succession has. Secondary succession is caused by disturbance in an ecosystem, but there is still soil, and it only takes hundreds of years for regrowth to happen.
Define food web
Food webs show the complex relationships of energy flow in an ecosystem. In a food web there is usually a variety of producers, consumers, and decomposers.
Define food chain
The path of energy from one organism to another in the ecosystem.

What is an ecosystem
All living and nonliving things, whether biotic or abiotic, living in an area together. These areas can be small or large.
Define abiotic factors
Non living parts in an ecosystem that directly impact the survival of the biotic factors in the ecosystem.
Why does 10% of an organism's energy move on?
The other 90% is used for body heat.
Who almost sassed a teacher?
Kennady
Give me three examples of primary succession.
A glacier stripping an area to bedrock, a volcanic eruption forming new land, or new sand dunes being formed.
What are some examples of secondary succession
Regrowth after a flood, regrowth after a forest fire, or regrowth after a tornado/hurricane.
What causes secondary succession
Disturbance in an environment
What are decomposers?
Decomposers break down dead plant or animal remains and turn them into nutrients that are released back into the soil. Producers then use these nutrients to make food/ energy for themselves.
What is a biome
A set of ecosystems that share similar characteristics like climate, plants, and animals.
What does primary succession start out with
Bare rock
What is the 10% rule?
In an energy pyramid 10% of the energy moves on from one trophic level to another.

What is a pioneer species
The first species to arrive in new lands during primary succession. Examples would be lichens or moss.
