Consumer-Resource Link
Consumer-Resource Link
Species interact within a community through a network where one species consumes resources and is, in turn, consumed by others.
What is a fundamental ecological interaction?
What is a fundamental ecological interaction?
A consumer-resource link is the basic connection where one species eats another, influencing populations.
Importance of Consumer-Resource Link
Importance of Consumer-Resource Link
This link serves as the foundation for building more intricate food chains and food webs within an ecological community.
Study Notes
- Species in a community exist within a network of interactions.
- Species act as consumers, eating resources.
- Species are also consumed by other species.
- These consumer-resource links construct complex food chains and food webs.
- Lectures will focus on the consumer-resource link.
- The focus on the the consumer resource link aids the development of a mechanistic understanding of species interactions.
- Mechanistic understanding of species interactions include predation and interspecific interactions.
