PRELIM - EXAM Flashcards
Are animals that consume dead organisms that have died from causes other than predation or have been killed by other predators.
Scavenger
The smallest unit of life
Cell
Degradation of the air that causes depletion of the ozone layer
Atmospheric Degradation
Degradation on the land with the excessive use of pesticides and fertilizers
Land and Soil Degradation
99% of the ultraviolet lights that come into our atmosphere are stopped by the..
Stratosphere
____ is an interdisciplinary academic field that integrates physical and biological sciences to the study of the environment
Environmental Science
is defined as surroundings that have the conditions for living organisms to operate
Environment
A group of individuals with same traits in one place
Population
A group of species with different traits in one place
Community
A development that meets the needs of the present without compromising the ability of future generations to meet their own needs
Sustainable Development
An act to promote environmental awareness through environmental education for other purposes.
RA 9512 National Environmental Awareness and Education Act of 2008
This law aims to adopt a systematic, comprehensive and ecological solid waste management program.
RA 9003 Ecological Solid Waste Management Act of 2000
TYPES OF CONSUMER
Consumers are also called
Heterotrophs
TYPES OF CONSUMER
Herbivores; animals feeding on plants.
e.g. rabbit, goat, deer
Primary Consumers
TYPES OF CONSUMER
Animals feeding on herbivores are called ____ or primary Carnivores.
e.g cats, foxes, snake
Secondary Consumers
TYPES OF CONSUMER
These are large Carnivores which feed on secondary consumers
e.g. Wolves
Tertiary Consumers
TYPES OF CONSUMER
They are also called omnivores these are largest carnivores that feeds on tertiary consumers and are not eaten up by any other animals
e.g. Lion and Tiger
Quaternary Consumers
Bacteria and fungi belong in this category. They break down dead organic matter of producers and consumers for their food and release to the environment the simple inorganic and organic substances.
e.g. earthworms, bacteria, beetles
Decomposers or Detritivores
The process in which individuals with certain traits are more likely to survive and reproduce under a particular set of environment conditions than those without traits.
Natural Selection
TYPES OF ISOLATION
Occurs when mutation and change by natural selection operate in the gene pools of geographically isolated populations.
e.g two closely related species of fish who live in different habitats not mating
Reproductive Isolation
TYPES OF ISOLATION
Occurs when different groups of the same species become physically isolated from another for a long period of time. e.g a mountain range prevents two types of goat from mating causing the gene pool to become less varied.
Geographic Isolation
A process whereby Earth’s life changes over time through changes in the genes of population in succeeding generation
Biological Evolution
TYPES OF SPECIES
An organism that helps hold the system together
e.g. human keyword: protect, provide, prevent
Keystone
TYPES OF SPECIES
An organism that is able to thrive in a wide variety of environmental condition and make use of variety of different resources
Generalist
TYPES OF SPECIES
An organism that lives by a limited diet and occupies a narrower niche.
Specialist
TYPES OF SPECIES
An organism that is self-sustaining population in a historic time
Native
TYPES OF SPECIES
Are organisms that have occurred outside their natural range. That natural range could be as far as another country or as near as a different region of the same country.
Non-native
TYPES OF INTERACTION
Both organism are benefited and obligatory ( +, +)
Mutualism
TYPES OF INTERACTION
oth organisms are benefited and not obligatory (+,+)
Protocooperation (Photocooperation)
TYPES OF INTERACTION
One organism benefits while the other is neither benefited or harmed (+,0)
Commensalism
TYPES OF INTERACTION
One organism benefits and the other is harmed (+,-)
Parasitism
TYPES OF INTERACTION
One organism is inhibited while the other is not affected (-,0)
Amensalism
TYPES OF INTERACTION
Boh organism are affected (-,-)
Competition
TYPES OF INTERACTION

Predation
MAJOR COMPONENTS OF BIODIVERSITY
- Functional Diversity
- Species Diversity
- Ecological Diversity
- Genetic DIversity
