SCX p2 Flashcards
bring energy from non-living sources into the community
Producers
eat the producers, which make them herbivores in most communities
Primary consumers
eat the primary consumers, which make them carnivores
Secondary consumers
eat the secondary consumers and followed by Terminal consumer
Tertiary consumers
What do you call a linear network of links in the food web starting from producers’ and ends at the
predator species?
Food Chain
What refers to a field of science which concerns about energy flow through living systems? It is also
the study of energy relationships and energy transformations and transductions in living organisms.
Bioenergetics
It is a natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Food Web
What type of food chain is referred to when an autotrophic organism occupy the first feeding level?
Grazing food chain
It is a graphical model of energy flow in a community.
Energy Pyramid
These are the plants and animals that first colonize a newly exposed habitat.
Pioneer Species
This succession begins in habitats where communities were entirely or partially destroyed by some
Secondary
It is the final succession stage of constant species composition which persists unchanged until
Climax Community
This term refers to the change in the composition of species over time.
Ecological Succession
It is a type of succession that occurs on substrates that has never been previously supported living
Primary
is a series of progressive changes in the species that make up a community over time.
Ecological succession
newly exposed or newly formed rock is colonized by living things for the first time.
primary succession,
an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance. FAQs
secondary succession,
is often described by the series of plant and animal communities that inhabit a region over
time. It occurs in some regions when climates change over thousands of years.
Succession
are the plant
and animals that are first to colonize a newly exposed habitat.
Pioneer species
is the change in the composition of species over time.
Ecological succession
is the final succession stage of constant species composition.
climax community
occurs on substrates that never previously
supported living things
Primary Succession
on the other hand begins in habitats where communities were entirely or partially destroyed by some kind of damaging event such as fire, floods, overgrazing, and deforestation.
Secondary Succession
is the introduction of harmful materials into the environment. These harmful
materials are called pollutants.
Environmental pollution
It is where pollution comes directly from one specific location.
Point Source
Pollution
It is the pollution that comes from large areas.
Non-point Source
Pollution
Reduces the quantity and quality of fresh water that is available for drinking and other
necessities of human beings
Water pollution
Natural air pollution- the natural impurities of air in the atmosphere include soil particles,
dust and pollen grain particles.
Air pollution
Occurs when the pollutants causing the pollution reduce the quality of the soil and
convert the soil inhabitable for microorganisms and macro organisms living in the soil.
Land/Soil pollution
Noise is random or unwanted sound. Unwanted sound can be caused by any kind of
sound, tones or harmonic sound.
Noise pollution
These results when excessive and unregulated amount of food additives, medicines,
drugs, alcohols, and cosmetics are introduced in the body.
Personal Pollution
This results when there is an overexposure to cosmic rays, ultra violet rays, infrared
rays, and rays from radioactive materials.
Radiation Pollution
A forest made up of tall trees with branch-less trunks. These types of forest are the major sources of timber and other forest products.
Dipterocarp
These forests are a tropical coniferous forest ecoregion of the Philippines in the western
Pacific Ocean.
Pine
It occupies about 165,000 hectares of the total land forest area of the country. Although
this classification of forest falls under the Dipterocarp, it is classified differently because
of its large total forest area.
Molave
This forest is usually found in some coastal areas. The Dungon, Agoho and Banulad
trees are common which is endemic to the Philippine islands.
Beach
These forests are found on the tidal flats of the coastal areas. They are good sources of
charcoals, firewoods and tannin. The mangrove ecosystem is a nursery ground. They
serve as buffer against typhoons and waves
Mangrove
Also known as cloud forest found throughout the higher parts of the mountains and
inhabited by many of the endemic wildlife of the Philippines.
Mossy
is known as the “green hell” because of its harsh environment, with about 80kg of green
mass per square meter
rainforest
