LT Quiz Food Chain

What are the levels of Organization?

1: Individual: A single organism

2: Population: a group of organisms of one type (same species) that live in the same area

3: Community: Multiple populations of different species that live and interact in the same area

4: Ecosystem: communities and the non living components in the area

5: Biome: Large region of Earth that has a certain climate and certain types of living things

Biosphere: the part of earth that contains all ecosystems

What is the difference between Biotic and Abiotic factors?

Biotic factors are the living parts of an ecosystem, including things that were once living and are now dead. Abiotic factors are the nonliving parts of an ecosystem.

What is a food chain?

A single pathway of energy transfer through an ecosystem as organisms eat one another. Arrows show the direction of energy flow, and the arrows point from what is being eaten to what it is being eaten by.

What is a food web?

A set of many interconnected food chains in an ecosystem, and is more complicated and more realistic than a food chain/ Shows more than one possible food source for each other.

What do all organisms occupy and what is that thing?

All organisms occupy a niche in their ecosystem, and it is the role that an organism plays in its habitat. Part of an organism’s niche is its ecological classification and trophic level.

What is the difference between a producer and a consumer?

Producers get energy from the sun (autotrophs) and consumers get energy from eating other organisms (heterotrophs).

What are the three types of consumers?

Herbivore- eats plants

carnivore- eats animals

omnivore- eats plants and animals

what is the difference between a decomposer and a scavenger?

decomposers break down dead organic material into non living matter, scavengers feed on dead organisms that were killed by other organisms.

What are the three feeding types?

Autotrophs- Self feeders, produce their food through photosynthesis

Heterotrophs- Depend on other organisms for their food

Decomposers: break down and absorb nutrients from dead, decaying organisms.

What is a trophic level and what are the four types?

an organism’s position in a food chain Organisms that feed on the same kind of food are at the same trophic level.

producers

Primary: eats producers

secondary: eats primary consumers

3: tertiary: eats primary and secondary consumers

quaternary: eats tertiary consumers

omnivores can be 2 and or 3.

What is an energy pathway?

shows the flow of energy from food in an ecosystem. Energy always starts with the sun, and only 10 percent of energy can be transferred.

What is an energy pyramid and the three ways to look at an ecological pyramid?

Energy pyramids show where and how much energy is found at each level, and the three ways to look at an ecological pyramid are energy, numbers, and biomass.
