| What is Ecology? | The scientific study of interactions among organisms and between organisms and their environment, or surroundings. |
| What does a biosphere contain? | It contains the combined portions of the planet in which all life exists, including land, water, and air, or atmosphere. |
| What is a species? | A group of organisms so similar to one another that they can breed and produce fertile offspring. |
| What is a population? | A group of individuals that belong to the same species and live in the same area. |
| What is a community? | An assemblage of different populations that live together in a defined area. |
| What is an ecosystem? | A collection of all organisms that live in a particular place , together with their nonliving environment. |
| What is an autotroph? | Plants, some algea, and certain bacteria that can capture energy from sunlight or chemicals and use that energy to produce food. |
| What is a heterotroph? | Organisms that rely on other organisms for their energy and food supply. |
| What is a food web? | The feeding relationships among the various organisms in an ecosystem that form a network of complex interactions. |
| What is a trophic level? | Each step in a food chain or food web. |
| What is biomass? | The total amount of living tissue within a trophic level. |
| What is the biogeochemical cycle? | The process in which elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another. |
| What is limiting nutrient? | When an ecosystem is limited by a single nutrient that is scarce or cycles very slowly. |
| What is weather? | The day-to-day condition of Earth's atmosphere at a particular time and place. |
| What is climate? | The average year-after-year condition of temperature and precipitation in a particular region. |
| What is the greenhouse effect? | The natural situation in which heat is retained by the layer of greenhouse gases. |
| What is are biotic factors? | The biological influences on organisms within an ecosystem. |
| What are abiotic factors? | Physical or nonliving factors that shape ecosystems. |
| What is a niche? | The full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions. |
| What is logistic growth? | The growth pattern in which a population's growth rate slows or stops following a period of exponential growth. |
| What is carrying capacity? | The largest number of individuals of a population that a given environment can support. |
| What is a demography? | The scientific study of human populations. |
| What is a demographic transition? | The change in a population from high birth and death rates to low birth and death rates, |
| What is the green revolution? | The development of highly productive crop strains and the use of modern agriculture techniques to increase yields of food crops. |
| What is a renewable resource? | A resource that can regenerate quickly and is replaceable. |
| What is a pollutant? | A harmful material that can enter the biosphere through the land, air, or water. |
| What is biodiversity? | The total sum of the variety of organisms in the biosphere. |
| What is biological magnification? | The increasing concentration of a harmful substance in organisms at higher trophic levels in a food chain or food web. |
