What is homeostasis?
The process by which living organisms maintain a stable internal environment despite external changes.
A method of communication between cells in an organism.
The ability of an organism to adapt to its environment over time.
The process of breaking down food into energy.
What is the role of decomposers in an ecosystem?
Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.
Decomposers produce energy through photosynthesis.
Decomposers are primary producers that create food for consumers.
Decomposers compete with plants for sunlight and nutrients.
What is biodiversity?
The total number of organisms in a given area.
The variety of life in a particular habitat or ecosystem, including the number of different species.
The study of how species interact with each other.
The process of evolution in different species.
Which definition best fits the term BIOTIC?
The study of the interactions between animals and their environment

Niche
Photosynthesis is important because...
it makes carbon dioxide
it makes food for the food webs
it makes water
it's not important
Oceans become more acidic because:
they absorb more carbon dioxide from the atmosphere.
they release more oxygen into the atmosphere.
they increase in temperature.
they decrease in salinity.
What impact does ocean acidification have on calcifying organisms like urchins?
It enhances their calcification process.
It reduces their ability to calcify.
It has no impact on their calcification.
It strengthens their skeletal structure.
9. What types of organisms are the major drivers of the nitrogen cycle? What do those major organisms do?
Bacteria and fungi, which decompose organic matter
Plants, which produce oxygen through photosynthesis
