Bio Terms Flash Cards
1. Ecosystem - A community of living organisms and their environment interacting as a system.
2. Biome - A large ecological area on the earth's surface, with flora and fauna adapting to their environment.
3. Population - A group of individuals of the same species living in a specific area.
4. Community - All the different populations that live together in a defined area.
5. Habitat - The natural home or environment of an organism.
6. Abiotic factors - Non-living chemical and physical parts of the environment that affect living organisms.
7. Biotic factors - Living components that affect the ecosystem, including plants, animals, and microorganisms.
8. Invasive species - Non-native species that spread beyond their original habitat and cause harm to the environment.
9. Niche - The role or function of an organism or species within an ecosystem.
10. Biodiversity - The variety of life in the world or in a particular habitat or ecosystem.
11. Food web - A system of interdependent food chains in an ecological community.
12. Trophic levels - The hierarchical levels in an ecosystem, comprising producers, consumers, and decomposers.
13. Producer - Organisms (like plants) that produce their own food through photosynthesis.
14. Consumer - Organisms that eat other organisms for energy.
15. Decomposer - Organisms that break down dead or decaying matter.
16. Organism - Any individual living entity.
17. Autotroph - Organisms that produce their own food from inorganic substances.
18. Heterotroph - Organisms that obtain food by consuming other living things.
19. Predation - The preying of one animal on others.
20. Symbiosis - Interaction between two different organisms living in close physical association.
21. Mutualism - A symbiotic relationship where both organisms benefit.
22. Commensalism - A symbiotic relationship where one organism benefits, and the other is neither helped nor harmed.
23. Parasitism - A relationship where one organism benefits at the expense of another.
24. Carrying capacity - The maximum number of individuals that an environment can support without degradation.
25. Density-dependent factors - Factors that affect population growth in relation to the population density.
26. Density-independent factors - Factors that affect population sizes regardless of population density.
1. Prokaryotic cell - A simple cell without a nucleus or other membrane-bound organelles.
2. Eukaryotic cell - A complex cell with a nucleus and organelles bound by membranes.
3. Organelle - Specialized structures within a cell that perform distinct processes.
4. Nucleus - The organelle that contains the cell's genetic material.
5. Mitochondria - The powerhouse of the cell, where energy production occurs.
6. Chloroplast - Organelles found in plant cells that conduct photosynthesis.
7. Endoplasmic reticulum - An organelle involved in protein and lipid synthesis.
8. Golgi apparatus - An organelle that modifies, sorts, and packages proteins for secretion.
9. Ribosome - The site of protein synthesis in cells.
10. Cell membrane - The semipermeable barrier surrounding the cytoplasm of a cell.
11. Passive transport - Movement of substances across a cell membrane without the need for energy.
12. Active transport - The movement of substances across a cell membrane using energy.
13. Diffusion - The passive movement of molecules from an area of higher concentration to an area of lower concentration.
14. Osmosis - The diffusion of water across a selectively permeable membrane.
15. Facilitated diffusion - The process of spontaneous passive transport of molecules across a cell membrane via specific transmembrane proteins.
16. Photosynthesis - The process by which green plants and some other organisms use sunlight to synthesize foods.
17. Metabolism - The chemical processes that occur within a living organism to maintain life.
18. Homeostasis - The ability of an organism to maintain stable internal conditions despite external changes.
1. Carbon cycle - The series of processes by which carbon compounds are interconverted in the environment.
2. Nitrogen cycle - The series of processes in which nitrogen and its compounds are interconverted in the environment and in living organisms.
3. Water cycle - The continuous movement of water on, above, and below the surface of the Earth.
4. Phosphorus cycle - The process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere, playing a crucial role in the growth of plants and the functioning of ecosystems.
