Biology Exam #1

Anything in the environment that causes an organism to respond:

The white hair of a polar bear:

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

A place where an organism lives

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

Can make their own food: producers

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

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

Heterotrophs are:

Autotrophs are:

Water evaporates from plant leaves

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

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

An organism's role or position in its environment:

A hypothesis is tested through a:

Observing chimps using tools to crack open nuts:

Eats only meat

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

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

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

A piece of data that is numerical

A group being exposed to the factor being tested:

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

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

The study of life

Water cools down and forms droplets

Eats both meat and plants

Must consume others to obtain energy: consumers:

A piece of data that is observed and is descriptive:

All of the organisms living together with their nonliving environment

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

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

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

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

An increase in size or mass

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

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

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

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

The study of:

Different populations living together in an area

Any information or evidence that is gathered:

The study of relationships between living and the nonliving environment:

The weight of the pumpkin is 5 pounds:

The reaction to a stimulus:

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

Single Celled

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

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

Anything that an organism needs is a:

Organism obtain this from food:

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

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

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

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

Eats only plants

The portion of the Earth where all life exists

A group of the same species in the same area

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

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

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

Many celled

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

The model that represents many interconnected food chains and pathways

Means life
