CORRECTLY LATEST UPDATE 2026
Ecology - Answers the study of the interactions between an organism and its environment. Involves
scientific study of the factors determining the distribution and abundance of organisms.

inhabited by living organisms.
Biome - Answers large, naturally occurring and occupying a major habitat.
Aquatic biome - Answers found within a body of water.
Freshwater - Answers defined by a very low concentration of salts; includes ponds, lakes, streams and
rivers.
Marine - Answers defined by a high concentration of salts; includes oceans and coral reefs.
Forests - Answers dominated by trees.
Tropical - Answers most biodiverse of all ecosystems; lacks seasonal climate, but can have wet and
dry seasons.
Temperate - Answers includes deciduous and evergreen forests; has a seasonal climate.
Taiga - Answers coniferous forests with cold climate including long winters and short summers;
mostly evergreen trees.
Grasslands - Answers dominated by grasses and are mostly devoid of trees and shrubs.
Temperate grassland - Answers present in temperate climates.
Tropical grasslands - Answers found in warm or hot climates; also referred to as savannas.
Wetlands - Answers dominated by aquatic plants and poorly draining soils.
Bogs - Answers wetland which accumulates dead organic material.
Fens - Answers wetland with alkaline and mineral rich soils.
Marshes - Answers wetland dominated by herbaceous vegetation.
Swamps - Answers wetland dominated by woody plants.
Ecosystem - Answers ecological level at which biotic and abiotic elements interact within a biome.
Community - Answers the assemblage of different species of flora and fauna living in an area.
Population - Answers groups of individuals of the same species occupying a particular area at the
same time.
Organism - Answers individual members of a species.
Producers - Answers produce energy or biomass through the process of photosynthesis.
Photosynthesis - Answers the process by which green plants convert carbon dioxide to plant tissue
from sunlight energy and water.
Cellular respiration - Answers All living things, including plants, respire; organisms require oxygen to
break down glucose in order to create energy.
Consumers - Answers obtain food and energy through the consumption of other organisms.
Niche - Answers Describes how organisms match abiotic environmental conditions and resources to
distribution of species and populations.
Competition - Answers Interaction between two organisms for the same resource, such as food,
space or light.
Predation - Answers when one species eats another for nutrition.
Parasitism - Answers when one species benefits while the other is harmed.
Mutualism - Answers when both species benefit from ecological interaction.
Commensalism - Answers when one species benefits while the other is unaffected.
Nutrient - Answers Chemical substance required by an organism for growth, reproduction and
maintenance of life.
Water / Hydrological Cycle - Answers Evaporation and condensation continually pulling water into
the lower atmosphere and then returning it once again as precipitation.
Evaporation - Answers The transformation of water into vapor.
Transpiration - Answers Occurs when plants release water vapor during photosynthesis and
respiration.
Oxygen Cycle - Answers Begins during photosynthesis when plants release oxygen into the
atmosphere.
Carbon Cycle - Answers Movement and release of carbon between the biosphere via photosynthesis
and respiration of plants and animals.
Producers - Answers Capture atmospheric carbon for photosynthesis.
, Decomposers and consumers - Answers Release carbon dioxide during respiration as organic
substances are oxidized.
Nitrogen Cycle - Answers Possible through the process of nitrogen fixation.
Nitrogen fixation - Answers Conducted by legumes, bacteria and nitrogen-fixing microorganisms.
Lightning - Answers An abiotic nitrogen fixation mechanism that splits diatomic nitrogen atoms
allowing them to bond with oxygen forming nitrogen dioxide.
Phosphorus Cycle - Answers Accomplished as plants absorb phosphorus through roots.
Ecosystem Management - Answers The effort by humans to manage ecosystems and their resources.
Ecosystem Monitoring - Answers Oversees air, water, soil, and wildlife to detect changes in
ecosystems.
Sustainability - Answers The act of responsibly using and managing resources in a way which supports
long-term ecological balance.
Habitat - Answers Areas in which animals, plants and other organisms live.
Provisional Services - Answers Resources harvested or extracted from the habitat which are used and
depended on.
Cultural Services - Answers Provide non-material benefits such as tourism, recreation, and spiritual
influences.
Regulating Services - Answers Provide benefits from the habitat that can regulate and maintain
ecological balance.
Supporting Services - Answers Provide processes which sustain the biosphere of the earth at large.
Habitat Loss - Answers The US has less than 5% of the native grasslands once covering earth.
Fragmentation - Answers Habitat broken up by human development such as roads, urban
developments, and bridges.
Degradation - Answers Quality of habitat reduced through events such as oil spills.
Destruction - Answers Complete loss of habitat through events such as building a shopping mall or
paving a wetland.
Marine Habitat - Answers Covers 75% of all the earth's surface, including seas, oceans and bays.
Freshwater Habitat - Answers Includes rivers, lakes, streams, wetlands and ponds, and contains more
organisms than marine habitats.
Terrestrial Habitat - Answers Defined by plant communities and geographic location, including
tundra, desert, deciduous forest, tropical rainforest, grasslands and taiga.
Yellowstone National Park Protection Act - Answers Grant signed the Yellowstone National Park
Protection Act.
First national park - Answers Yellowstone is recognized as the first national park.
National refuge - Answers Established in 1903 by Theodore Roosevelt.
Forest Service - Answers Established by Theodore Roosevelt in 1905.
National Park Service Act (The Organic Act) - Answers Established in 1916 to protect current and
future national parks.
National Resources Conservation Plan - Answers Established by Franklin D. Roosevelt, focused on
land and resource protection.
Civilian Conservation Corps - Answers Created to restore damaged environments and improve
infrastructure.
Preservation - Answers Non-use of natural resources; limiting human impacts on a habitat.
Restoration - Answers Repairing or restoring a habitat which has been damaged.
Education - Answers Sharing knowledge about how to make good ecological choices.
Management - Answers Taking care of a habitat by intervening to maintain necessary ecological
processes.
Ecosystem services - Answers Forests provide ecosystem services locally and globally.
Improving air quality - Answers Improved by trees.
Carbon sequestration - Answers A mature tree can absorb more than 48 pounds of carbon dioxide
annually.
Oxygen production - Answers A single tree can produce about 260 pounds of oxygen each year.
Filtering out air pollutants - Answers Leaves can absorb sulfur dioxide, nitrogen oxides, and
particulate matter from burning fuel.
Improving water quality - Answers Water filtration through tree roots can stop pollutants from being
spread through erosion or runoff.
Natural filtering - Answers As water passes through tree roots, sedimentation occurs.
