Answer Details
Organisms in an ecosystem are usually grouped into two main categories based on how they obtain their food or energy.
The first group is called producers, which are usually plants or algae that make their food through a process called photosynthesis, using energy from the sun, carbon dioxide, and water.
The second group is called consumers, which include animals that eat other organisms to obtain their energy. Consumers can be further divided into three subcategories based on what they eat:
- Herbivores: animals that eat plants
- Carnivores: animals that eat other animals
- Omnivores: animals that eat both plants and animals
Parasites are organisms that live on or inside other organisms, known as hosts, and obtain their food from them. Epiphytes are plants that grow on the surface of other plants and obtain their nutrients and moisture from the air and rainwater.
Saprophytes are organisms, usually fungi and bacteria, that obtain their food by decomposing dead organic matter, such as dead plants and animals.
Therefore, the correct answer to the question is "producers and consumers".
