What is Biological diversity
It is also known as biodiversity and it is the variety of the earth's species, or varying life-forms
100
What is biological evolution and name a mechanism for biologic evolution
The process whereby the earths life changes over time through changes in genes of populations of organisms. mechanism is natural selection.
100
give an example of a biome
forests, desserts, etc.
100
What is resource partitioning
It is when species compete for similarly scarce resources.
100
What is carrying capacity
the number of people, other living organisms, or crops that a region can support without environmental degradation
200
What is functional Diversity
functional diversity is the biological and chemical processes such as energy flow and matter recycling needed for the survival of species, communities, and ecosystems.
200
What is natural selection and give an example.
where individuals with certain traits are more likely to survive and reproduce. an example would be moth coloration
200
How do humans affect biodiversity give 2 examples
Habitat Destruction & Hunting, genetic diversity, species transfer,
200
What is the difference between an adaptation and an evolution
Adaptation generally refers to change that leads organisms to be suited to their local circumstances in some way, while evolution typically reefers to changes in genes.
200
Name a method of counting species
Find how many exist in a small block by tagging and multiply it out or use the capture and re capture method
300
What is a species, and give an example
A group of similar organisms that can breed and produce fertile offspring. (Humans)
300
Give an example of a foundation species
kelp
300
What are two classifications of biomes and give examples of those biomes.
terrestial and aquatic, and these include the types of biomes known as deserts, forests, grasslands, savannas, tundra, and freshwater environments
300
Name 4 of the 5 ways species interact with each other
Introspective Competition, Predation, Parasitism, Mutualism, Commensalism.
300
In order to determine snail populations, 340 snails were captured, tagged, and released. Later, 420 snails were captured. Of the 420 snails, 16 were already marked. What is the size of the snail population?
8925

With the help of technology which ways do we use earths biodiversity? name 4
We use biodiversity to provide us with food, wood, fibers, bio-fuels, medicines. biodiversity also plays a critical role in providing us with ecosystem services that preserve the quality of the air and water, maintain the fertility of topsoil, decompose and recycle waste, and control populations of pests.
400
What is the difference between a a keystone species and a foundation species?
A foundation species provides the foundation of a habitat, while a keystone species maintains the habitat
400
What is an indicator species
Species that serve as early warnings that a community or ecosystem is being degraded.
400
What is mutualism and give an example
the interaction that benefits both species. an example would be birds that ride on the backs of large animals
400
Two examples of Evolution by Random Processes
Mutation, genetic drift, bottleneck effect, founder effect
500
What are the four components of the earths biodiversity
The four components are the genes they contain, the ecosystems in which they live, and the ecosystem processes of energy flow, and nutrient cycling that sustain all life. (Ecological, functional, genetic and species diversity.)
500
What leads to biological evolution by natural selection
Mutations and changes in the genetic makeup of populations.
500
What are the 4 major roles species play in ecosystems
Native, Nonnative, Indicator, Keystone
500
name four of the six ways that prey have developed to stay alive from predators.
Camouflage, Chemical, warning collaboration, mimicry, deceptive looks, deceptive behavior.
500
What are the names of the three distributions.
clumped, uniform, random
