Terms in this set (51)
An organism that can make it's own food.
Example- green plants.
An organism that eats other organisms for food.
1st level consumer-herbivores.
2nd level consumers-omnivores and carnivores.
3rd level consumers-tertiary-top of the food chain.
A carnivore that eats other animals for food.
An animal that a predator feeds upon.
A close relationship between organisms where at least one benefits.
Organism-a parasite- that shares a relationship with a host and causes it harm.
Ticks, mosquitoes, tapeworms, sea lamprey.
When both organisms benefit from their symbiotic relationship.
Sea anemones and clown fish.
Cow birds and cattle.
When one species benefits from a symbiotic relationship and the other species is not helped or harmed.
A bird building a nest in a tree.
Non-living parts of an ecosystem.
Rocks, air, water.
Living parts of an ecosystem.
Plants, animals, fungi.
Changes that occur in an area where no ecosystem had existed. Soil does not yet exist.
Examples-Retreating Glaciers, new lava, barrier beaches.
Changes that occur on preexisting soil after it has been has been disrupted or destroyed.
Forest fires, floods, the Dust Bowl.
Represents the flow of food energy from lower level organisms like producers to higher level organisms like tertiary consumers.
Groups of overlapping food chains.
One cell. Single cell organisms.
More than one cell.
Small organisms that are unicellular with no nucleus.
Multi-cellular organism where cells contain a nucleus.
Examples- animals, plants, fungi, protista
The process by which molecules move from an areas of high concentration to low concentration.
The diffusion of water molecules through a selectively permeable membrane.
A balanced or stable system.
A complex process by which the body's internal environment is kept stable in spite of changes in the external environment.
Example-sweating, shivering, vomiting.
Located outside cell membrane and provides structure and stability to cell. Found in plants but not animal cells.
The organelle that stores food, water and other materials for a cell
A cell structure that controls which substances can enter or leave the cell. Protective membrane of organelles in animal and human cells.
Control center of a cell that directs it's activities.
Helps move materials around the cell. It has a jelly like consisitency.
Organelle in plant cells that captures sunlight and uses it to produce food in the form of sugars like glucose.
Powerhouse of the cell. Provides energy.
Organism that breaks down dead organisms.
Self-nourishing organisms that create their own food. Also called producers. Plants.
Cannot make own food. They must eat other organisms to live. Also called consumers. Cows, insects, humans.
A trait that will appear in an offspring if parent has that trait. Example-brown eyes are a dominant trait.
A trait that does not appear in an offspring. Example-blue eyes are recessive.
A series of paired statements-yes or no questions- that helps identify different species.
A system that is made up of the vessels and the muscles that help and control the flow of the blood around the body. These include the heart, arteries, veins, and capillaries.
Supplies the circulatory system with oxygen. Includes the nose, trachea, bronchial tubes, lungs, and alveoli.
Protects our internal organs and gives us shape. Makes red and white blood cells in the large bones.
Allows us to move and maintain posture. Moves your body, and helps it perform functions. There are three types of muscles. Smooth, skeletal, and cardiac.
Breaks down the food we eat by mechanical and chemical means and allows nutrients to enter the circulatory system.
Discards waste products in the body. A group of organs including the kidneys, liver, skin, intestines, and lungs that purify the body by the elimination of waste matter..
Regulates growth and metabolism. Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use or metabolism by body cells.
An enormous network of specialized cells found throughout your body. It's the control center for all body functions. Composed of neurons-cell, axon, dendrite, central nervous system-brain, spinal cord. Responsible for five senses, heart rate, breathing, speech, and movement.
Consists of the skin and related structures such as hair and nails. Forms a covering of the body, helps regulate body temperature, and contains some of the structures necessary for sensation. Protects body from damage and infection.
Body system responsible for processes by which plants and animals produce offspring. The system of organs that allow for the creation of children. Includes the testes, ovaries, uterus, penis, and vagina.
A trait that allows an organism to change to it's environment. The adjustment or changes in behavior, physiology, and structure of an organism to become more suited to an environment.
A level of classification that includes Animals, Plants, Fungi, Protists and Monera.
A group of organisms that share similar characteristics of a body plan
The theory that cells form the fundamental structural and functional units of all living organisms. Cells are the basic unit of structure in every living thing.
A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents.
A reproductive process that involves only one parent and produces offspring that are identical to the parent.
