Biology Exam #1

An organism's role or position in its environment:

Many celled

A relationship between two organisms where one benefits, the other is neither harmed nor helped

Different populations living together in an area

Factor that results from or depends on changes to the independent variable:

The model that represents a sequence of organisms that feed on each other

All of the organisms living together with their nonliving environment

A relationship between two or more organisms where they benefit from each other:

Eats both meat and plants

The white hair of a polar bear:

The sudden drop in temperature caused me to get goosebumps. What is the response:

The sudden drop in temperatures will cause me to get goosebumps. What is the stimuli?

The study of relationships between living and the nonliving environment:

Eats only plants

Anything that an organism needs is a:

A piece of data that is numerical

Must consume others to obtain energy: consumers:

A factor that remains fixed while the independent and dependent variable changes

Water cools down and forms droplets

A group of organisms that can breed with each other to produce fertile offspring

Process where bacteria capture and change nitrogen into a form usable by plants

Anything in the environment that causes an organism to respond:

Process where bacteria convert fixed nitrogen into nitrogen gas and release into the atmosphere

Can make their own food: producers

The weight of the pumpkin is 5 pounds:

The group that doesn't receive the factor being tested and is the standard used for comparison

A relationship between two organisms where one benefits and the other is harmed.

Means life

A group being exposed to the factor being tested:

Process in which most autotrophs use the sunlight to make their own food

Any inherited characteristic that result from changes to a species over time.

Each level in a food chain, web, or pyramid:

The study of life

The reaction to a stimulus:

Observing chimps using tools to crack open nuts:

All of the living factors in an organism's environment:

Type of reproduction that happen without sperm and eggs. Includes only one parent

Organism obtain this from food:

The portion of the Earth where all life exists

The model that represents many interconnected food chains and pathways

Water evaporates from plant leaves

The condition being deliberately changed by the scientist or the variable you do something to:

An increase in size or mass

Autotrophs are:

Single Celled

Eats only meat

Interaction between the same kinds of organisms where they help each other

Water fall from the clouds in the form of rain, snow, sleet, hail

The process of natural changes in shape or form that take place during the life of an organism.

A close relationship that exists with two or more species living together:

A large group of ecosystems that the same climate and have similar type of climates

The regulation of an organism's condition to maintain life:

Water is turned from a liquid to a gas (water vapor form)

A place where an organism lives

A piece of data that is observed and is descriptive:

An interaction where one hunts the other and kills it to fulfill their energy needs

Heterotrophs are:

Process in which some autotrophs make their own food using energy stored in chemical bonds

A hypothesis is tested through a:

All of the nonliving factors in an organism's environment:

A group of the same species in the same area

Type of reproduction that includes the union of sperm and egg. Two parents

Interaction that takes place between different and same kinds of organisms-compete for resource

Any information or evidence that is gathered:

The study of:
