What kind of ecosystem do you see? In an ecosystem, everything is interconnected. Producers are plants that get their energy from the light of the sun – and nutrients from the soil – to make ...

In an ecosystem, the organisms that can harness energy to create that fuel are known as producers, or autotrophs. They take inaccessible forms of energy like sunlight, and convert them into usable ...

Food chains and food webs interconnect organisms within an ecosystem. Producers, such as plants and algae, form the base of the food chain by using photosynthesis to convert sunlight into energy.

For example, the amount of carbon and energy fixed in photosynthesis by plants and other producers (e.g., productivity) constrains the amount of consumers an ecosystem may support. Because of this ...

Scientists have determined that at least six new aquatic species have been thriving under an Antarctic ice shelf.
