Predator: an animal that preys on other organisms
Prey: an animal hunted or killed by another for food
Symbiosis: beneficial relationship between different organisms or groups
Competition: to compete
Ecosystem: biological community in which organisms interact
Carbon cycle: the circulation of carbon from the atmosphere into organisms and back
Nitrogen cycle: when nitrates from soil are absorbed by plants which are eaten by animals that die and decay returning the nitrogen back to the soil
Oxygen cycle: cycle of the oxygen in which it is turned into carbon dioxide in animal respiration and then changed back into oxygen by photosynthesis
Population: the number of individuals inhabiting a specific area
Diversity: differing from one another
Energy pyramid: shows energy loss in each level
Consumers: animal that feeds on other organisms
Producers: organisms that produce their own food
Limiting factor: environmental factor or factors that limit growth or abundance
Decomposers: organisms that break things down
Food chain: describe eating relationships between different species
Biotic: living factors
Abiotic: nonliving factors
Community: interacting population
Variable: factor that is able to be changed
Evidence: proof
Inference: conclusion reached by obtaining evidence and by reasoning
Quantitative: measuring something by the quantity
Qualitative: measuring something by the quality
Organelles: organized structures in a cell
Photosynthesis: process used by plants to make food
Respiration: cycle of breathing in oxygen and breathing out carbon dioxide
Cellular respiration: where organisms get energy from molecules and takes place in the cells and tissues in which energy is released and carbon dioxide is produced
Osmosis: when molecules from a solvent passes through a semi permeable membrane And makes both sides of the membrane equal
Diffusion: transport of molecules from a higher concentration to a lower concentration by random molecular motion
Active transport: movement of molecules to a higher concentration
Homeostasis: remaining stable
Cell theory: All organisms are composed of one or more biological cells
The cell is the basic unit of organization of organisms
All cells come from preexisting cells
Organic: to do with carbon based molecules
Carbohydrate: to contain carbon hydrogen and oxygen
Fermentation: chemical breakdown of a substance
Protein: compound composed of a chain of amino acids
Fat: oily greasy substance
Nucleic acid: biological molecules essential for life that allow organisms to transfer genetic information from one generation to the next
Chlorophyll: green substance in plants that absorbs sunlight energy to make photosynthesis
Cell membrane: inside cell wall and is semi permeable
Nucleus: organelle containing genetic material and instructions
Cell wall: only found in plant cells and located outside of cell membrane
Solvent: the liquid in which a solute is dissolved into a solution
Solute: substance to be dissolved
Adhesion: adhesion of water is how well it sticks to other substances.
Cohesion: of water is how well it sticks to itself it is caused by hydrogen bonds
Microorganism: microscopic organism
Organ: a part of an organism
Organ system: system made up of many organs working together
Organism: an individual plant animal or single celled living organism
Hormonal modification: alterations in hormonal behavior
Stomata: pores in plants that help transfer gases
Tissue: cellular organization
Structure: arrangement or construction of elements
Function: activity or purpose for a thing
DNA: genetic material
Replication: copying
Fertilization: the joining of genetic material between two organisms
Dominant trait: trait that is stronger or shown
Recessive trait: trait that is not shown
Genetic engineering: direct manipulation of genes
Phenotype: trait that can be seen physically
Genotype: trait that is found inside your genes
Sexual reproduction: reproduction by two organisms
Asexual reproduction: reproduction by splitting or pitching off of the original organism

Evolution: change overtime
Fossil record: collection of fossilized artifacts
Geologic record: layers of rock
Molecular: to consist of molecules
Homologous: the same
Vestigial structures: structure that may have been used in ancestors
Recombination: rearrangement of genetic material
Hierarchy: organization of levels of importance with the most important at the top
Classification scheme: descriptive information for a hierarchy arrangement
Theory: set of principles on which a practice is based
Natural selection: the process in which the best survive
Adaption: to make changes to be able to survive in a certain environment
Speciation: formation of new species during evolution
Biodiversity: variety in life
Taxonomy: classification system
Kingdom: highest level in classification
Virus: nonliving thing that causes harm
Protists: kingdom made up of mostly single celled organisms including bacteria
Fungi: spore producing organisms that feed on organic matter
Animal: living organisms that feed on organic matter and have specialized sense organs and nervous system that can react to stimuli
Dichotomous: to choose between two choices to be able to classify an object or organism
