In Biology and Ecology, a resource is a substance or object in the environment required by an organism for normal growth, maintenance, and reproduction. Resources can be consumed by one organism and, as a result, become unavailable to another organism. For plants key resources are sunshine, nutrients, water, and place to grow. For animals key resources are food, water, and territory.
Key resources for plants
- Carbon dioxide
- Microsite (ecology)
- Photosynthetically active radiation
- Seed dispersal
