Why can’t a hawk survive in an ecosystem that contains only plants?
Because hawks are carnivores and need to eat other animals to get energy.
If decomposers stopped working, how would that indirectly affect photosynthesis in plants?
The soil would lose nutrients, causing plants to weaken and produce less food through photosynthesis.
Why can we say that photosynthesis and respiration are opposite but connected processes?
Because photosynthesis produces oxygen and glucose used in respiration, while respiration releases carbon dioxide and water needed for photosynthesis.
Why are flowers considered both beautiful and essential for plant survival?
Because besides being colorful, they produce seeds that allow the plant to reproduce and continue its species.
