What is the difference between direct and indirect competition?
What is the difference between direct and indirect competition?
- Direct competition involves individuals reducing exploitation efficiency of another, while indirect competition involves populations depressing one another through shared resources. (correct)

Study Notes
- Parasitism involves a predator (parasite) living in symbiosis with its prey (host).
- Hosts may have different parasites that depend on various factors such as abiotic and biotic environments.
- Parasites can manipulate host behavior to complete their lifecycle and transmission to the next host.
- Hosts have various defenses against parasites, such as immune system, biochemical defenses, and defensive symbionts.
- Parasites have mechanisms for host evasion and tolerance.
- Parasites can affect host population growth rate, range, abundance, and community interactions.
- Competition occurs between individuals or populations of the same or different species, affecting their survival, growth, or reproduction.
- The niche refers to the environmental conditions that meet the abiotic and biotic requirements of a species.
- Positive interactions include mutualism, commensalism, and various types of benefit such as food, shelter, and protection.
- Community structure can be described by species richness, evenness, diversity, composition, and interactions between species.
