What is a independent variable
Its what I/you change
What is symbiosis
Symbiosis - a close relationship between two different kinds of organisms, or living things. There are three basic types of symbiotic relationships: mutualism, commensalism, and parasitism.
What is a natural disaster
Natural Disasters - natural scenarios involving disease, disability or death on a large scale among humans, animals and plants due to microorganisms like bacteria, virus or toxins.
What is a species
Species - a group of similar organisms that are able to reproduce.
What is evolution
Evolution - the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
What is a dependent variable
What happens naturally
What is a biotic factor
Biotic Factors - all the living things in the ecosystem.
What is Conservation
Conservation - is the act of protecting Earth's natural resources for current and future generations.
What is populations
Populations - is a group of organisms of the same species, all living in the same area and interacting with each other.
Who was Charles Darwin
Charles Darwin - was an English naturalist, geologist, and biologist, widely known for contributing to the understanding of evolutionary biology
What is a control
• Control - is an experimental group where NOTHING is changed. Control Groups are used for comparison.
what is the Law of the Conservation of Mass
Law of the Conservation of Mass - mass is neither created nor destroyed.
What is Eutrophication
Eutrophication - occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.
What is Communities
Communities - all of the different populations of living things that interact with one another in an area.
What is Natural Selection
Natural Selection - the process where organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
what is a theory
a system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation
What is the carbon cycle
Carbon Cycle - the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
What is Phototropism
Phototropism - the direction of a plant or other organism in response to light, either toward the source of light
What is Ecosystems
Ecosystems - is a community of interacting organisms (biotic factors) and their environment (abiotic factors).
What is EMBRYOLOGY
EMBRYOLOGY - can also be used as evidence to relate organisms to one another.
What is a constant
a condition or factor that is assumed to have one value, or remain unchanged throughout a particular investigation
what is the water cycle
the path that all water follows as it moves around Earth in different states. Liquid water is found in oceans, rivers, lakes—and even underground. Solid ice is found in glaciers, snow, and at the North and South Poles. Water vapor—a gas—is found in Earth's atmosphere.
What is Ocean Acidification
Ocean Acidification - decreasing levels of pH in the ocean, which makes the sea more acidic. It is the long-term change in seawater chemistry due to the absorption of carbon dioxide from the atmosphere. Roughly 30 percent of human-made CO2 is absorbed by the oceans.
What is biomes
Biomes - is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.
What is adaptation
Adaptation -the process by which a species becomes fitted to its environment
