Ecosystems & Factors
This term describes a community of living and nonliving components that interact in an environment.
What is an ecosystem?
These organisms make their own food through photosynthesis.
What are producers?
This interaction occurs when one organism hunts and eats another.
What is predation?
This model shows how energy moves from one organism to another.
What is a food chain?
This is a statement based on what is directly seen, measured, or recorded.
What is an observation?
Plants, animals, fungi, bacteria, and decomposers are examples of these ecosystem components.
What are biotic factors?
These organisms obtain energy by eating other organisms.
What are consumers?
This interaction happens when organisms rely on the same limited resources.
What is competition?
This is the correct basic pattern of a food chain.
What is Producer → Primary Consumer → Secondary Consumer → Decomposer?
This is a conclusion based on observations and prior knowledge.
What is an inference?
Sunlight, water, soil, air, temperature, and rocks are examples of these components.
What are abiotic factors?
Herbivores, carnivores, and omnivores are types of these organisms.
What are consumers?
This interaction benefits both organisms involved.
What is mutualism?
This model shows interconnected food chains within an ecosystem.
What is a food web?
Temperature readings and number of organisms are examples of this type of data.
What is quantitative data?
Both biotic and abiotic factors are necessary for an ecosystem to do this successfully.
What is function?
These organisms break down dead materials and return nutrients to the environment.
What are decomposers?
This interaction benefits one organism while the other is not significantly affected.
What is commensalism?
Energy does this as it moves through an ecosystem.
What is flows?
Color, texture, and smell are examples of this type of data.
What is qualitative data?
These two types of factors work together to determine what organisms can survive in an ecosystem.
What are biotic and abiotic factors?
This role is responsible for recycling nutrients back into the ecosystem.
What are decomposers?
This interaction benefits one organism at the expense of another.
What is parasitism?
As energy moves through trophic levels, it does this at each level.
What is decreases?
Soil compaction, litter, pollution, and plant removal are examples of this.
What is human impact on ecosystems?
