Keywords
Ecosystem Interactions between organisms, and between these organisms and their environment.
Chlorophyll A green pigment found in the chloroplast that traps radiant energy from the sun.
Radiant energy Light energy that comes from the sun.
Glucose A sugar that is a product of photosynthesis.
Destarch When starch in a leaf is converted & moved to other parts of the plant
Respiration The series of chemical reactions by which plants & animals release the potential chemical energy
trapped in them.
Species A group of similar organisms that can interbreed with each other to produce fertile offspring, but
cannot breed with other species.
Interbreed Able to mate with each other to produce viable offspring.
Ecologist A scientist who studies the relationships between organisms and their environment.
Abiotic components Non-living parts of an ecosystem.
Biotic components Living parts of an ecosystem.
Physiographic Factors associated with the physical nature of an area (Height above sea level)
Altitude The height or location of any object above a certain base (Sea level/ground level)
Gradient The degree to which a slope ascends or descends.
Habitat The place where an organism lives.
Food chains The natural process in which one living thing is eaten by another, which is in turn eaten by another
and so on.
Feeding relationships Interaction between biotic components.
Food webs The different food chains in an ecosystem are interconnected to form a complex web of feeding
interactions.
Trophic level The particular feeding/nutritional position occupied by different organisms in an ecosystem.
Carrying capacity The maximum number of individuals that a particular environment can support.
Eroded The gradual loss of soil by natural elements (wind/rain).
Adaptation A form/structure modified to fit a changed environment.
Extinct The organism dies out and no longer exists anywhere in the world.
Naked eye Seeing something without the aid of magnifying lens or microscope.
Microscopic Instrument using a series of lenses that increase the size of the image when it reaches the eye.
Microbiologist Scientist who studies micro-organisms.
Pathogenic Capable of causing diseases.
Infectious Something that can be spread from organism to organism.
Immune system Your body’s defence system, helps protect you from infections.
Cosmopolitan Found almost everywhere.
Anthrax A bacterial disease usually found in sheep and cattle; can be transferred to humans.
Rabies Viral disease affecting nervous system of all warm blooded creatures & almost always leads to death.
Pharmacologist Person who studies how drugs work in the human body.
Antibiotic Medicine used to treat bacterial infections.
Control Used for comparison in an investigation; factor being investigated is not included in control.
Reproduction Process in which parent organisms give rise to new living individuals.
Hormones Chemicals in the body.
Menstruation The monthly flow of blood and lining of the uterus.
Implantation When the zygote embeds itself into the inner lining of the uterus.
Promiscuous Human who has many different sexual partners.
Eukaryotic cells Cells that make up plants and animals.
Cells Smallest living unit that makes up a living organism.
Organelles Small parts of a cell that each have their own functions and characteristics.
, Photosynthesis
- Process whereby green plants use radiant energy + CO2 + water in series of chemical reactions to make glucose.
- Chloroplasts in green plants contain chlorophyll which is used to trap radiant energy and convert it to glucose,
which is stored in the plant as starch.
- Starch, cellulose, chemical compounds are produced from glucose enable processes such as growth &
reproduction.
Respiration
- When energy is released from food.
- Mitochondria
- Breaks down energy rich food substances, glucose using oxygen.
Glucose + oxygen energy + carbon dioxide + water
Ecology
- Study of the interactions of organisms with one another and with their physical & chemical environment.
1) Population
Group of organisms of the same species that live in the same area & are able to interbreed.
2) Communities
Different species of organisms /different populations that share a common area and are interdependent
on each other.
3) Ecosystems
- Consists of a community and its environment.
- Living organisms affect each other and their env. (vice versa)
- Biotic and abiotic
4) Biosphere
- All ecosystems combined
- Bios: where living things can exist.
Ecosystems
Abiotic Biotic
Air & wind: - All the living organisms and the wate they produce.
- Gases are imp. For life processes. (pho+res) - Most varies and easily changed pats of eco.
- Moving air for birds migrating - Influenced by: disease, population, a/biotic,other org.
Temp, sunlight, shade: - The survival of individual organisms & populations
- Temp determines the type of life the eco support. depend on ability of org to adapt to changes.
- Sunlight & shade affects temp
Soil, stones, rocks: Ecosystem:
- Woodlice pref – moist, sticky soil - Stable sys. made up of a comm. of org. which interact
- Scorpions, centipedes – loose, dry soil with env.
Steep/gentle slope:
- Altitude, slope of land and position of area in area in relation to sun or winds impact eco.
- Slopes affect surface temp of soil (North facing are warmer) (S. Eastern: rain bearing winds-forests in places.)
- Gradient-steep slope won’t hold lots of water, soil, rocks. (North slopes: lots sunlight) (gentle north for veg.)
