What are the two primary sources of energy that power living systems?
The 2 primary sources of energy that power living systems are photosynthesis and chemosynthesis.
What’s the primary source of energy?
Primary sources of energy are found in nature. They include coal, natural gas, water and wind. The Sun is the original energy source for all of these things.
How does energy flow from one thing to another?
A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem.
What do decomposers use as a source of energy?
Decomposers (Figure below) get nutrients and energy by breaking down dead organisms and animal wastes. Through this process, decomposers release nutrients, such as carbon and nitrogen, back into the environment. These nutrients are recycled back into the ecosystem so that the producers can use them.30
Is a bacteria a decomposer?
Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.8
Does Java moss float or sink?
Like other mosses, Java moss has no true roots; instead, it absorbs nutrients primarily through its leaves. It will grow free-floating or will send out rhizoids to attach itself to rocks, decorations, and driftwood, as well as to gravel or sand.5
