Click on the flashcard to see the answer
What is ecology?
Ecology is the branch of biology that studies the interactions between organisms and their environment.
What is an ecosystem?
An ecosystem is a community of living organisms and their non-living environment interacting as a system.
What are biotic factors?
Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms.
What are abiotic factors?
Abiotic factors are the non-living components of an ecosystem, such as temperature, sunlight, and soil composition.
What is a food chain?
A food chain is a sequence of organisms in which each organism feeds on the one below it in the chain.
What is a food web?
A food web is a network of interconnected food chains that shows the flow of energy and nutrients in an ecosystem.
What is a producer?
A producer is an organism that can convert sunlight into chemical energy through photosynthesis.
What is a consumer?
A consumer is an organism that obtains energy by consuming other organisms.
What is a decomposer?
A decomposer is an organism that breaks down organic matter into simpler substances, returning nutrients to the environment.
What is a population?
A population is a group of organisms of the same species that live in the same area and can interbreed.
What is a community?
A community is a group of populations of different species that live in the same area and interact with each other.
What is a habitat?
A habitat is the specific environment in which an organism lives and obtains the resources it needs to survive.
What is biodiversity?
Biodiversity refers to the variety of life in an ecosystem, including the number of different species and their abundance.
What is the water cycle?
The water cycle is the continuous movement of water on, above, and below the surface of the Earth.
What is the carbon cycle?
The carbon cycle is the process by which carbon is exchanged between the atmosphere, biosphere, geosphere, and hydrosphere.
What is an ecological pyramid?
An ecological pyramid is a graphical representation of the trophic levels in an ecosystem, showing the relative energy or biomass of each level.
