Question

What is the difference between energy and matter when it gets processed through a system? How do different species interact with each other? (relationships between organisms like competition, etc…) What are some of the major threats to the biosphere and why is conservation biology important?

Answer 1

Energy is the property that a matter has. Same quantity of matter has different amount of energy and hence it represents different states of matter. In a system energy and matter both are conserved within the system. Which means energy and matter can change forms but cannot be created or destroyed. Energy and matter both are cycled in a system and there different forms interact.

Species interactions include four main types i.e. mutualism, commensalism, competition, and predation.

Competition : It is a relationship in which different individuals or populations attempt to use the same limited resource . Each individual has less access to the resource and so is harmed by the competition. Each species negatively affects the other.

Predation : An organism that feeds on another organism that is fed upon is the prey. Species A feed on species B.

Mutualism : A close relationship between two species in which each species provdes a benefit to the other. Each species is helpful to the other.

Commensalism : A relationship in which one species is neither harmed nor helped. Species A benefits from species B, but B is unaffected.

Some of the major threats to biosphere are humans activies, and loss of habitat, deforestation, desertifiation, increased wildlife trading, climatic changes, marine environment, etc.

Conservation of biology is very important because it develops methods for manageing a small range of species for the recreation. It provides broader approach and has long term preservation of biological diversity. protecting the wildlife and promote biodiversity. It is management of nature and earth biodiversity which helps in protecting species and their habitats, and ecosystems from extinction and erosion of biotic interactions.
