Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).
Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.
The first step: Oxygen in water is oxidized (light energy required)
The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).
Answer:
A. People cut down the trees in a forest, leaving less habitat for squirrels.
Explanation:
A large percentage of the depletion of an ecosystem can be attributed to anthropogenic or human activities. Ecosystems are naturally known to support or inhabit life. For example, many trees in an ecosystem are homes to living organisms such as birds, insects, snakes etc.
However, according to this question, an exemplary description of how humans can decrease an ecosystem's ability to support life is when "people cut down the trees in a forest, leaving less habitat for squirrels". This act will decrease the forest's ability to support life.
