Final answer:
The statement that accurately describes one way plants depend on other organisms is that bacteria fix nitrogen into forms usable by plants. This symbiotic relationship allows plants to obtain essential nutrients for growth and supports biogeochemical cycles within ecosystems.
Step-by-step explanation:
The correct statement that describes one way that plants depend on other organisms is C) Bacteria fix nitrogen into forms that plants can use. This dependency is a result of a symbiotic relationship where bacteria living in the soil or in the root nodules of certain plants convert nitrogen from the atmosphere into a form that plants can absorb and use to synthesize proteins. This process is known as nitrogen fixation. Plants utilize the fixed nitrogen to grow healthy tissues and make the nutrient available for other organisms in the ecosystem. While plants do provide habitats for animals and are a source of energy through consumption, the key way plants depend on other organisms as stated in the question is through the process of nitrogen fixation carried out by bacteria.
Plants play a crucial role in various biogeochemical cycles. They are not just producers in food chains, using photosynthesis to harness energy from the sun, but also rely on decomposers and nitrogen-fixing bacteria to obtain necessary nutrients like nitrogen, which is limited in its available forms in nature.
