What is abiotic and examples?
All non living things
Eg: Sand, temperature and light

A population is a group of living organism that are the same species, living in the same place at the same time.
Benefits of an ecosystem:
- Plants and animals work together to help maintain the balance of gases in the air
- Insects birds and bats help pollinate plants
- Some organic decompose organic matter
- Wetlands and forests clean water
What are the relationships within a species?
- Collaboration
- Mating
- Competition
What are the Relationships between different species?
- Mutualism
- Commensalism
- Parasitism
What is collaboration?
Occurs when organism cooperate with each other to ensure their survival.
What is mating?
Between members of the same species produces offspring, thus ensuring the survival of the species.
What is competition?
Occurs when organism use the same limited resource.
What is mutualism?
A relationship between two organisms in which both organism benefit.
What is commensalism?
A relationship in which one organism benefits and the other organism is not affected.
What is parasitism ?
A relationship in whihc one organism (the parasite) lives in or on the body of another (the host). The parasite benefits but the host is harmed.
