Ecosystems
The study of how living things interact with each other and their physical environment.
What is ecology?
Autotrophs, such as plants and algae, produce their own food.
What are producers?
Two or more organisms living together that benefit one another in their living situation.
What is mutualism?
Layer of earth where life exists.
What is the biosphere?
The natural home of a living thing, including where it finds its food and shelter. (desert, forest, lake)
What is a habitat?
An organism that obtains its food by feeding on other organisms or organic matter.
What is a consumer?
Two organisms living in a relationship where one benefits, and the other is neither harmed nor benefited.
What is commensalism?
Areas of the world with similar climate, animals, and plants.
What are biomes?
An organism's function in its habitat, including its relationship with other organisms.
What is a Niche?
Some bacteria can make their own food through this process, other than photosynthesis, which involves converting chemicals to usable forms of energy.
What is chemosynthesis?
Two organisms living in a relationship where one is harmed and the other benefits.
What is parasitism?
All the organisms of one species within an community.
What is a population?
A system made up of all living organisms interacting with one another and their environment.
What is an ecosystem?
What are herbivores?
In a situation where a human has worms, what would each be called?
What is the host and the parasite?
Smaller sections within a biome.
What is an ecosystem?
Living organisms within an ecosystem that affect the other living organisms there.
What are biotic factors?
Meat-eaters
What are carnivores?
Two examples of ecological cycles?
What are the Water Cycle, Carbon Cycle, and the Nitrogen Cycle?
Smaller sections within an ecosystem.
What is a community?
Nonliving components of an ecosystem that affect the organisms living there.
What are abiotic factors?
Eat plants and animals
What are omnivores?
Coldest and driest biome on Earth.
What is a tundra?
Break down wastes or dead material from both producers and consumers, making the materials bound up in the dead bodies available to the ecosystem again.
What are decomposers?
The biome is located near the Earth's equator and receives around 400 inches of rain each year.
What is the tropical rainforest?
The trophic level to which photosynthesizers belong.
What is the first trophic level?
This biome doesn't get extremely cold or hot, and contains some of the richest soil on earth, primarily covered in grass.
What are temperate grasslands?
The trophic level to which herbivores belong.
What is the second trophic level?
The first organisms that establish a home after ecological succession, such as after a volcanic explosion.
What is the pioneer species?
Feed on calcium reach limestone.
What is a calcivore?
