Biodiversity Flashcards
It is a term that is used to describe the differences among organisms
Biodiversity
Three components that make up biodiversity
- Species
- Ecosystem
- Genetic
It refers to a collection of living and non-living organisms and their interaction with each other
Ecosystem
It refers to the variety of different types of species found in a particular area
Species
It refers to the variations among genetic resources of the organism
Genetic
It is the ability of an organism to adapt to the changes in its environment
Adaptation
It is the resilience to withstand changes that may occur in the environment
Stability
Value of Species
- Direct Economic
- Indirect Economic
- Aesthetic
The product of a species are sources of food, medicine, clothing, shelter, and energy
Direct Economic
There are benefits produced by the organism without using them
Indirect Economic
It is a type of biodiversity wherein many kinds of organisms live in an area
High Biodiversity
It is a type of biodiversity where few kinds
of organisms live.
Low Biodiversity
It shows the sequence on how organisms feed on one another, showing how energy is transferred.
Food Chain
It is a graphical representation showing the flow of energy in a trophic level in an ecosystem.
Energy Pyramid
It is the group of organisms within an ecosystem which occupy the same level in a food chain. The
Trophic level
It is a group of living organisms belonging to same species that live in a certain geographical area.
Population
It shows us the trend whether a certain population is increasing or decreasing. It can be affected by the following factors: birth rate (natality), death rate (mortality), immigration (moving into an area), emigration (moving away from an area), geographical space
and availability of resources, and others.
Population Growth
organisms reproduce at the constant rate. -depicts J-shaped curve in graph
Exponential Growth
organisms reproduce increasingly but
gradually decreases due to a finite, or
limited, amount of resources. depicts S-shaped curve in graph
Logistic Growth
It is the maximum population that a certain area or environment can support.
