Adaptations
What do Adaptations allow organisms to do?
Survive and Reproduce
What is natural selection
When organisms adapt to better survive and reproduce in a given environment.
What is Carrying Capacity?
The carrying capacity refers to the number of individuals the environment can support over a long period of time.
how many colours are in the rainbow
7
What is Evolution
What happens if a organism is not well adapted?
They will not reproduce and will die off
What is the first step in the natural selection process
There is a variation in the species
What are the 2 types of limiting factors?
Direct and Indirect
what shape is used for a stop sign?
an octagon
What are the evidences for evolution
Anatomy
Fossils
Embryology
DNA
What do Functional Adaptations Effect?
How the body functions?
Give an example of a variation?
Well done
What does Abiotic factors mean, and give and example
Non-living factors, such as sunlight, water, temperature, fire, climate ect.
What does a funambulist walk on?
A tight rope
What is embryology
The study of the development of embryos
A thorny devil having spikes on its back to collect water is an example of what type of adaptation?
Structural Adaptation
How does a Variation become the dominant trait?
The other variant dies out due to competition and not being able to reproduce. essentially dying out leaving one trait.
What does it mean by dependent limiting factors and what is one example?
Dependent limiting factors are factors that depend on living organisms. this includes relationships between organisms, plant and animal population ect.
Area 51 is located in which state?
Nevada
what does it mean by homologous
something that is there but no longer needed for function due to evolution.
When Eucalyptus are digested in large amounts by animals it would be fatal. However the koala has a digestive system allowing it to break down large quantities of leaves.
What type of Adaptation is this?
Functional/ Physiological Adaptation
Why does a variation become a dominant trait?
Because it is a trait that allows the species a better chance to survive and reproduce
When reading a graph on an species population how do you know the species has reached the carrying capacity of the ecosystem?
Usually a straight line parallel with the axis will indicate that a species has reached carrying capacity.
cynophobic is the fear of what?
dogs
