What would happen to oxygen levels on Earth if plants stopped making photosynthesis?
Oxygen levels would decrease, and most living organisms that depend on it for respiration would die.
Why would a plant die even if it receives water and nutrients but no sunlight?
Because without sunlight, photosynthesis cannot occur, so the plant cannot make glucose (its food) and will lose energy.
How does the structure of root hairs increase the efficiency of photosynthesis indirectly?
Root hairs absorb more water and nutrients, which are essential raw materials for the photosynthesis process.
Why would the disappearance of decomposers eventually cause all other living organisms in an ecosystem to die?
Because decomposers recycle nutrients back into the soil, and without them, plants cannot get the nutrients they need to grow, so all consumers would lose their food source.
If sunlight energy cannot flow directly to consumers, how do they still receive the Sun’s energy indirectly?
Through the food chain — consumers eat producers that have stored the Sun’s energy in glucose.
How is the human circulatory system connected to the process of photosynthesis in plants?
The oxygen and glucose produced by plants are used by the human circulatory system to supply energy to body cells.
