APES Stack 1

TermDefinition
Environment A place in which someone or something lives.
Environmental Science An academic area that studies environmental problems and human impacts on the environment using ecology, geology, meteorology, biology, chemistry, engineering, and physics.
Ecosystem A biological community of organisms that interact with one another and their physical surroundings.
Biotic All the living processes of an ecosystem.
Abiotic Physical rather than biological; not derived from living organisms.
Environmentalist A person who is concerned about or advocates for environmental protection.
Ecosystem Service The direct and indirect contributions of ecosystems to human wellbeing.
Economic Services Government-provided services and resources meant to help struggling individuals connect with support that can help them meet their needs.
Biodiversity The variety of life in the planet or in a given environment or ecosystem.
Genetic Diversity The ability of a population to produce organisms with different genotypes.
Species A community of living beings made up of comparable individuals capable of sharing genes or interbreeding.
Species Diversity A measure of biological diversity in an ecological community.
Speciation The formation of new and distinct species in the course of evolution.
Greenhouse Gases A gas that contributes to the greenhouse effect by absorbing infrared radiation.
Anthropogenic Things that have been generated by humans.
Sustainability The ability to be maintained at a certain rate or level.
Biophilia An innate and genetically determined affinity of human beings with the natural world.
Ecological footprint The impact of a person or community on the environment.
Hypothesis A proposed explanation for a phenomenon.
Control group A group of subjects in an experiment or study that does not receive the treatment or factor under study.
Sample size The number of observations or replicates that are selected from a population for a statistical study.
Replication (during experimentation) The repetition of a scientific experiment or trial to obtain a consistent result.
Theory A supposition or a system of ideas intended to explain something.
Surface tension The tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
Capillary Action The tendency of a liquid in a capillary tube or absorbent material to rise or fall as a result of surface tension.
Acid A chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red.
Base A conceptual structure or entity on which something draws or depends.
pH A figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline.
Chemical reaction A process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
Law of conservation of matter States that the mass of an object or collection of objects never changes over time, no matter how the constituent parts rearrange themselves.
Carbohydrate Any of a large group of organic compounds that includes sugars, starch, and cellulose, containing hydrogen and oxygen in the same ratio as water (2:1) and used as structural materials and for energy storage within living tissues.
Protein Any of a class of nitrogenous organic compounds that have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms.
Lipid A broad group of organic compounds which include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, phospholipids, and others.
Nucleic acid A complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
DNA/RNA (DNA) and ribonucleic acid (RNA) are complex molecular structures that control all hereditary characteristics of cells and thus of organisms.
Renewable Energy Energy from a source that is not depleted when used, such as wind or solar power.
Nonrenewable Energy Energy derived from finite resources that are not replaced quickly enough to keep up with the speed of consumption.
Chemical energy Energy stored in the bonds of chemical compounds.
First law of thermodynamics Distinguishes in principle two forms of energy transfer, heat and thermodynamic work for a system of a constant amount of matter.
Second law of thermodynamics The branch of physical science that deals with the relations between heat and other forms of energy.
