What is igneous rock?
What do we call the change from a solid to a liquid?
What is melting?
What type of relationship benefits one organism and harms the other?
What is parasitism?
What do we call all the living and nonliving things interacting in an environment?
What is an ecosystem?
What do we call organisms that make their own food using sunlight?
What are producers (or autotrophs)?
This type of rock forms from layers of sediment that are pressed and cemented together.
What is sedimentary rock?
What is the process of a liquid becoming a gas?
What is evaporation (or vaporization)?
What is the difference between a predator and prey?

Which term describes the nonliving parts of an ecosystem, like sunlight, water, and temperature?
What are abiotic factors?
This type of organism breaks down dead plants and animals and returns nutrients to the soil.

What is metamorphic rock?

What is deposition?
In this symbiotic relationship, both organisms benefit.
What is mutualism?
This term describes a group of the same species living together in one area.
What is a population?

False — it is a biological interaction, but not symbiosis because the prey dies.

A food chain shows one energy path; a food web shows many interconnected food chains.
