Which of these statements is true of ecosystems? a animals do not travel from one ecosystem to another ecosystem b the total amo
unt of energy in an ecosystem does not change c air cannot be used by organisms once the air moves out of the ecosystems d matter lost by one ecosystem is gained by the surrounding environment
I think the answer is B. I think energy decreases as it moves up tropic levels when it is lost as the organisms from one level consume the organisms in the other.
Explanation:
It can't be A because animals do travel from one ecosystem to another. It's migration. It's not C because air can be used by organisms as once as the air moves out of their ecosystem because air is everywhere and the organisms need air to breathe and to live. D is definitely incorrect because matter can't be created or destroyed. Remember that an ecosystem is the organisms physical environment. I hope this answers your question.
Glucose is produced by plants through photosynthesis. In this process, the plant uses light energy from the Sun to convert carbon dioxide and water into glucose and oxygen. Algae and certain bacteria and other unicellular organisms also produce glucose through photosynthesis.
Answer:There are many advantages of immobilisation, one of which is that the enzymes can be reused – catalysing the same reaction many times. Binding the enzymes to a surface also makes them more stable and less likely to denature (lose their shape).
