What is the ultimate source of energy for all ecosystems?
Daniel AllenThe Sun
The sun is the biggest and natural source of energy, providing it in the form of light to autotrophs like green plants, which will produce food by photosynthesis.
The energy then is transferred to secondary consumers by eating those plants, and that energy is again transferred again to tertiary consumers by eating those secondary consumers. About

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Why is a food web a more realistic representation of a community as compared to a food chain?
- When energy is transferred from one trophic level to the next, about 90% of the energy is lost. If plants produce 1,000 kcal of energy, how much of the energy is passed to the next trophic level?
- What are some examples of primary productivity?
- What is the difference between parasites and predators?
- How is a food chain related to energy flow within an ecosystem?
- 98% accuracy study help
- Covers math, physics, chemistry, biology, and more
