4th Quarter Assessment Review 2018

Limiting factors that effect a population no matter the density/size (natural disasters).

Blood type is an example of a common ___ allele trait. There are 3 different alleles.

Movement of organisms into a new population/range.

Evolution in which species that once were similar become distinct/different from the original.

When overuse of land and limited water turn farmland into land that cannot support plant life.

A body structure in an organism that no longer serves a purpose but was useful to an ancestor.

When organisms with favorable variations in nature survive and pass on their DNA to offspring.

Traits controlled by genes located on the X and Y chromosomes are called _________ traits.

Lowest level of ecological organization in which living and nonliving things are interacting.

The arrows in food chains and food webs represent the transfer of ____

A lava flow leaves behind bare rock- what will take place to build up a new ecosystem?

A community formed when succession has completed and a stable community has formed.

In incomplete dominance, red x white parents = ___ offspring.

Gray-brown haze formed by chemical reactions between pollutants from automobiles and industry.

Biome with the least amount of precipitation, extreme temperature changes, plants store water.

Animals that eat the dead carcasses of other animals.

_______ evolve, not individuals.

Each node on a cladogram represents the last point at which groups of organisms shared a common

Each step in the transfer of energy in a food web.

Biome where ground is frozen into permafrost. Short, cool summers and long cold winters.

Adaptation where a harmless species resembles a harmful species in order to avoid predators.

These organisms use only cellular respiration to produce energy within their cells.

These effect a population more the larger/more dense it is (competition, food, disease, water).

Biome with coniferous trees in the north, mild summers and long/bitterly cold winters.

The maximum number of individuals of a particular species that an environment can support.

Organisms such as bacteria and fungi that chemically break down organic matter

What type of growth curve is this?

When humans split ecosystems into pieces by developing the land.

Most all sex-linked disorders are found on the ___ chromosome.

When humans choose to breed certain animals in order to receive offspring with specific traits.

An adaptation that enables species to blend in with their surroundings.

Non-living parts of an environment. (ex: water, sunlight, soil)

Resources such as coal, oil, and natural gas that take a very long time to be replaced.

A group of similar organisms that can breed and produce fertile offspring.

When a chemical such as DDT increases in concentration the further it moves up the food web.

Biome home to most biodiversity, warm year round, most precipitation, trees form a tall canopy.

The ability of an organism to survive and reproduce under a range of environmental conditions

A relationship in which one organism benefits and the other is harmed.

A relationship in which one organism benefits and the other receives nothing

These live in the soil and roots of certain plants and carry out nitrogen fixation.

This occurs whenever a physical barrier divides a population.

Autotrophs such as plants and algae are also called____.

______ alleles cause both phenotypes to be produced, both traits are seen at the same time.

When an existing community is damaged by a disaster and then builds back up again.

The variety of living things in an area.

These organisms use both photosynthesis and cellular respiration to produce energy in cells.

Total amount of living material at each trophic level.

Most of his theory of evolution has been supported by modern day scientists.

A special kind of wetland where a river meets the sea, mixture of fresh water and saltwater.

All physical and biological factors an organism needs to survive.
