Energy flow is the amount of energy that moves through a food chain
chemical cycling is the flow of elements and compounds between living organisms and the physical environment
Answer:
The concentration of water is greater outside the cell than inside the cell.
Explanation:
In living cells, water moves by Osmosis across the cell membrane, which acts as the semi-permeable membrane. Osmosis is the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).
The contractile vacuole of this freshwater organism helps regulate water intake and exit by storing excess water. According to osmotic flow, water will flow into the organism via its cell membrane (semi-permeable membrane) because the concentration of water outside the cell is high than inside the cell, hence, this causes an osmotic gradient causing water to flow into the cell. The water that flows into the cell is stored in the Contractile vacuole.
Explanation:
1. A decrease in the number of greenhouse gases that humans produce will result in lowered global temperatures. This will allow the ice sheets in the polar regions to increase increasing also albedo.
2. Using light-colored building materials on houses and pavement in urban centers will work towards increasing albedo as more sunlight is refelcted back by built environments.
3. Decreased deforestation/increase in aforestation increases the earth’s sirface albedo because vegetation reflects back more sunlight than the earth’s bare surface.
Autotrophs obtain energy and nutrients from sun and inorganic substances
