Ecology Flashcards
(40 cards)
The term used to describe the exchange of carbon (in various forms, e.g., as carbon dioxide) between the atmosphere, ocean, terrestrial biosphere, and geological deposits.
Carbon cycle
What is the correct term for plants releasing water from their leaves, which then evaporates?
Transpiration
The technique used for collecting bottom-dwelling marine organisms (e.g., shellfish) or harvesting coral, often causing significant destruction of reef and ocean-floor ecosystems.
Dredging
The illegal killing of animals or fish, a great concern with respect to endangered or threatened species.
POACHING
It occurs in neritic zones of warm, tropical water, dominated by cnidarians, very productive and protects land from storms.
Coral reefs
Occurs in benthic zone; diverse, unusual organisms; energy comes not from light but from chemicals released from the magma
Deep-sea vent
A terrestrial biome that is usually vertical stratification with trees in canopy blocking light to bottom stratA.
Tropical forest
It occurs when water channels and reservoirs become clotted with silt and mud, a side effect of deforestation and soil erosion.
Siltation
A science that deals with applying ecological concepts and principles to the design, development and management of agricultural environment
Agroecology
The effect of biota on global chemistry, and the cycles of matter and energy that transport the earths chemical components in time and space
Biogeochemistry
The increase of concentration of a substance
Biological magnification
This deals with the ecological role of biological chemicals used in a wide range of areas including defense against predators and attraction of mates.
Chemical ecology
Why are ecosystems with high biodiversity more stable than those with few species?
They recover from negative events more quickly.
What combine with atmospheric moisture to create acid precipitation?
sulfur dioxide and nitrogen dioxide
What is the organism, usually an animal, that feeds on plants or other animals
CONSUMER
This of the following refers to meeting the needs of the present without compromising the ability of future generations to meet their own needs.
Conservation
A group of organisms interrelated by the fact that each member of the group feeds upon the one below it
FOOD CHAIN
What gas is released during photosynthesis?
OXYGEN
A biological interaction between individuals of two different species, where each individual derives a fitness benefit.
MUTUALISM
Uses energy from the sun or energy stored in chemical compounds to produce energy
Autotrophs
The Department of lnterior and Local Government (DILG) responsibilities includes
Provision of transportation, security and fire protection amenities
Plant or animal species whose presence, abundance, and health reveal the general condition of its habitat.
Bio-indicators
The total weight or volume of living matter in a given area or volume.
BIOMASS
The chemicals which cause plants to lose their leaves artificially; often used in agricultural practices for weed control, and may have detrimental impacts on human and ecosystem health.
Defoliants
