Science Term 2 Biology Flashcards
List the 3 domains
Bacteria, Archaea, Eukarya
What are the 6 Kingdoms?
Eubacteria, Archaebacteria, Protista, Animalia, Plantae, Fungi
What are the 7 characteristics of life?
(Mrs Gren) Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion, Nutrition.
List the levels of the Linnaean Classification System.
(DKPCOFGS) Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
What is the order of the food chain/ web.
Primary producer, Primary Consumer, Secondary consumer, Tertiary consumer, Decomposers
What are the different symbiotic relationships?
Competition, commensalism, mutualism, parasitism, predation
How does an Energy Pyramid work?
Shows that 10% of energy is passed onto the next trophic level. Producers have 100% of energy.
How does Photosynthesis work?
Water, sunlight and Carbon Dioxide make Glucose, and oxygen.
What is biodiversity?
A measure of how many different species or the variety of species in an ecosystem.
Define Organism
A living thing.
What is the difference between a food chain and a food web
Food chains go from left to right, food web go from the bottom to the top
Define Classification/Taxonomy
The way to define and classify an organism.
Categorising organisms based in their physical characteristics.
What is a community?
All the living organisms that live within a given area and interact with each other.
What is an Ecosystem?
An Ecosystem is a biological community of interacting organisms and their physical environment. This includes all the biotic and abiotic factors in a specific region which interact.
What is a biome?
A major ecological community of organisms adapted to a particular climatic or environmental condition on a large geographic area in which they occur.
Define Biosphere
Broadest level of biological organisation. All life/ organisms on earth, biotic. The regions of the surface and atmosphere of the earth or another planet occupied by living organisms.
What is the Linnaean Classification system used for?
Grouping and classifying of organisms by their physical features.
What are the two different types of Dichotomous Keys?
Tabular and Branched.
What are Dichotomous Keys used for?
Help Scientists (with hints) to classify organisms.
Define Niche
The role of an organism within its environment.
Define a Habitat
A habitat is the place or location within the ecosystem where an organism lives.
Examples of Ecosystems
Deserts, Jungles, Tundra, Reefs, Lakes, Rivers, Wetlands, Urban, Agriculture.
What are some Australian Eco-Systems?
Rainforests, Deserts, Grasslands, Bushland, Reefs.
What are Abiotic and Biotic?
Biotic is Alive and Abiotic is not alive.
What are examples of Abiotic factors?
Sunlight, wind, temperature, salinity.
What are Heterotrophs and Autotrophs?
A Heterotroph is an organism that has to eat for it’s food and energy. (Animals) An Autotroph is an organism that has it’s own process and make it’s own food without having to eat for it. (Plants using Photosynthesis)
Define Producers
Producers are an organism that generated glucose from sunlight via photosynthesis to make energy via cellular respiration.
Define a Consumer
Consumers are organisms that consume other organisms to gain glucose and other chemicals to make energy via cellular respiration.
Define Decomposers
Decomposers are an organism that breaks down organic material and absorbs other chemical to make energy via cellular respiration.
What is a commensalism symbiotic relationship?
One Organism benefits and the other neither benefits or is harmed.
What is a mutualism symbiotic relationship?
Where both Organisms benefit.
What is a parasitism symbiotic relationship?
One organism benefits and the other is harmed
What is a predation symbiotic relationship?
One organism eats the other
What is a symbiosis relationship?
Where there is an interaction between two organisms.
What is a Biomass pyramid?
It calculates the total quantity or weight of organisms in a given area or volume.
What is a population pyramid?
Shows population of each organism in each trophic level.
How does Cellular Respiration work?
oxygen + gluecose - energy- carbon + water + APT
Where does the extra energy go in Energy Pyramids.
Organisms don’t eat every part, the energy doesn’t get absorbed, the energy gets released through cellular respiration.
What is the difference between Eukaryotic and prokaryotic cells?
Eukaryotic cells have a nucleus (Brain) Which stores DNA, this is all the kingdoms except for bacteria. Prokaryotic cells don’t have a Nucleus, this is archaebacteria and Eubacteria.
What is the difference between unicellular and multicellular organisms?
unicellular organisms are only made of one cell. Multicellular organisms are made of more than one cell (complex)
What are examples of unicellular organisms?
Bacteria and archaea bacteria are unicellular, fungi and protists can be either multicellular or unicellular
What are examples of multicellular organisms?
Animals and plants are multicellular, fungi and pro teeth can either be unicellular or multicellular.
