Answer:
Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills. In single-celled organisms such as protists, and small multicellular organisms, essential molecules will move to where they're needed by diffusion.

Answer:
The correct answer is: we would lack the energy we need to function.
Explanation:
Glucose is a type of sugar that gives us energy. When we eat something that contains glucose, our body releases insulin, a hormone from our pancreas, which absorbs the excess glucose in the blood and stabilizes sugar levels. When insulin is released, it travels through the bloodstream to the body's cell. After that, the cells convert glucose into energy to use right then or store it for later use.
In other words, if our bodies could not metabolize glucose we would be hungry and exhausted because we would not get enough of the other nutrients (like proteins and fibers) to sustain our energy.
They construct dams and create an ecosystem for other species . Because of their dam building nests become available for birds, fish population increases and waterfowl population goes up
