vo
an organism that produces organic compounds from simple substances such as water and carbon dioxide; an autotroph.
producer
an organism that derives the organic compounds and energy it needs from the consumption of other organisms; a heterotroph.
consumer
I eat only meat
carnivore
I never eat meat
herbivore
I like to eat both meat and plants
Omnivore
a biological community of interacting organisms and their physical environment.
ecosystem
Relating to or denoting heritable characteristics which are controlled by genes that are expressed in offspring even when inherited from only one parent.
What is Dominant Allele?
Describes the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
What is weather?
Describes a distinct sequence of nucleotides forming part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid molecule which a cell (or virus) may synthesize.
what is a gene?
Decribes one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
What is allele?
I consume dead organisms that have died from causes other than predation or have been killed by other predators.
What is a scavenger?
I am an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
What is a decomposer?
I am also known as a trophic or ecological pyramid, is a graphical representation of the energy found within the trophic levels of an ecosystem.
What is a energy pyramid?
This describes the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
What is natural selection?
Relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent.
What is recessive allele?
These are organisms whose cells have a nucleus enclosed within a nuclear envelope.
What is a Eukaryote?
These are unicellular organism that lacks a nuclear membrane-enclosed nucleus.
What are Prokaryotes?
This describes any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.
What is tissue?
This describes a group of organs that work together to perform a certain function in an organism's body.
What are body systems?
This decribes the weather conditions prevailing in an area in general or over a long period.
What is climate?
This is a position or role taken by a particular kind of organism within its community. Such a position may be occupied by different organisms in different localities, e.g., antelopes in Africa and kangaroos in Australia.
What is a Niche?
This is the tidal mouth of a large river, where the tide meets the stream.
What is an estuary?
This is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations
What is artificial selection?
This has one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
What is an allele?
This is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
What is Phenotype?
