It is the interaction between organisms and their environment.

Trophic pyramid:
Law of tolerance:
The amount of something a organism can take before it dies.
Law of minimum:
The minimum a organism need to survive
Hydrological system:
It describes the movement of water above, on, and below the earth surface.
Para- magnetism
It's the ability of rock dust to store energy from light, that can be released  to the surrounding plant roots known as para- magnetic energy.
Succession:

It's the action of one party (person or product) being replaced by the other that has become absolete, incompasitated, retired or deceased.
 Simbiosis:
Intimate relationship between different species living together.

Mutualism: both organisms benifit from the relationship.
Commensialism: one organism benefit, the other one does not get affected.
Parasitism: One organism benifits and the other oneis harmed.
Organisms: 
Living things-multi and unisellular.
Needs: energy, water, air, shelter, nutrients.
Ecosystems:
All individuals of the same species = population, populations together= communities, communities+abiotic part= ecosystem.
Termite mound:

Go deep down inside the ground.
Different compartments
The queen lives in one compartment where she gets fed and have babies.
Termites take leaves and twigs, under ground and secretes a fluid on it, wait for it to get fungus then eat it.
Earth pigs scratch it open and eat termites

Termites: Fertalise soil, and decompose.
