Interactions in the Environment Flashcards
What are the diffrent trophic levels?
- Producers (all green plants that produce their own organic food)
- Consumers (mainly animals depended on producers or other consumers)
- Decomposers (bacteria and fungi)
The diffrent types of consumers include:
* primary consumers (herbivores)
* second consumers (carnivores)
* tertiary consumers (carnivores eating secondary consumers)
What are the five types of interation in communities?
- Predation (predators)
- competition (Two or more individuals compete for food, water and so on)
- Mutualism (symbiotic relationship where both organisms benifit)
- Commensalism (symbiotic relationship where one benifits where the other neither beniifits or is harmed)
- Parasitism (symbiotic relationship where one benifits and other is harmed)
What are the two types of competition?
- intraspecific=takes place between individuals of the same species
- Interspecific= takes place between two diffrent species
What are the two diffrent types of parasits?
- Ectoparasites=lives on the external surface of host’s body
- Endoparasites= lives inside host’s body
What are some social organsation strategies?
- herds or swarms as anit-predation strategy
- packs as a successful hunting strategy
- Sharing of tasks
What is Ecological succession?
Ecological successions refers to the sequence of communities, where one community replaces another over times, resulting in long-term changes to the ecosystem.
These changes conitnue until a complex, stable ecosystem developes. this is known as the climax of succesion
The first plants and animals are known as the pioneers or pioneer communities
