Biological Diversity
Which areas have high biodiversity ecosystems?
rainforest, coral reef
Define Adaptations, and what are the types of adaptations?
Adaptations are inherited traits or characteristics—either physical or behavioral—that help an organism survive, reproduce, and thrive in its environment.
Structural (or Physical) Adaptations
Behavioral Adaptations
Physiological Adaptations
What are Species
Species are groups of living organisms that:
Share similar characteristics, and
Can interbreed to produce fertile offspring under natural conditions.
Which areas have low biodiversity ecosystems?
artic tundra, arid dessert
Define structural adaptations.
Structural (or Physical) Adaptations
Physical features of an organism’s body.
Example: Thick fur in polar bears to insulate against cold.
what is population
A group of individuals of the same species living in a specific geographic area at the same time.
How humans influence biodiversity positively?
wildlife sanctury, hunting(overpopulation), breeding programs
Define Psychological adaptations.
Physiological Adaptations
Internal body processes that improve survival.
Example: Snakes producing venom for hunting or defense.
How Habitat Destruction Affects the Organization of Species?
Habitat destruction unravels the natural structure (organization) of species in an ecosystem—leading to species loss, broken food chains, and ecological imbalance.
How humans influence biodiversity negatively?
cleear cutting, poaching, urbanization
How does genetic diversity within a species contribute to its survival?
Genetic diversity within a species contributes to its survival by increasing its ability to adapt to changes in the environment.
What is an ecosystem?
An ecosystem is a community of living organisms interacting with each other and their non-living environment. It includes both biotic (living) and abiotic (non-living) components that depend on each other. Energy flows through the ecosystem, and nutrients cycle within it.
What is behavioural adaptation?
Behavioral adaptation refers to the actions or behaviors that organisms develop over time to help them survive and reproduce in their environment.
ex: Bird migration, Herding
What is diversity index? And how it is measured?
is used to measure health of an ecosystem.
DI= #of organism/#of differnet species
The higher the number, the better.
what is ecosystem diversity
Ecosystem diversity is the range of different habitats, biological communities, and ecological processes in the environment.
