Things that create their own energy
What is producers (plants)
The basic unit of heredity passed from parent to child. This unit is made up of sequences of DNA
What is a gene
Cell walls are present only in this type of cell.
What is plant cell.
A group of organisms linked in order of the food they eat, from producers to consumers. and from prey, predators, scavengers and decomposers.
What is food web?
An animal that hunts and eats other animals is called this.
What is predator.
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
Organisms whose cells lack a nucleus and other organelles
What is a prokaryote?
Organisms in food webs are grouped in categories. These three categories include:
What is Producers, Consumers and Decomposers
Change in an organism or its parts that fits it better for the conditions of its environment.
What is adaptation?
The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
What is a phenotype
Any cell or organism that possesses a clearly defines nucleus.
What is an eukaryote?
a graphical representation of the energy found within the trophic levels of an ecosystem, where the bottom level is the producers which contain the largest amount of energy. This graphical representation is presented in the form of a triangle.
What is an energy pyramid?
This is a mechanism of evolution. It describes the fact that Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success.
What is Natural Selection?
Three limiting factors that control population growth.
What is food, water and space/shelter.
Material of which animals and plants are made, consisting of specialized cells and their products.
What is tissue?
Animals that produce milk for their offspring and have hair are called this.
What is mammals.
What are the seven levels of classification.
What is kingdom, phylum, class, order, family, genus, species.
The genetic makeup of an organism
What is a genotype
Organisms that have certain traits that are favorable for survival reproduce and pass those traits onto their offspring. Over time, the trait increases in the population. This is called ______________.
What is natural selection
Organisms that help in the break-down of dead plants or animals.
What is decomposer.
