Life began this long ago on Earth.
Note: Answer must be within range presented in class (inclusive).
3.5-4 billion years ago
The most broad taxon.
Domain.
The bottom of an energy pyramid is occupied by these types of organisms.
A random change in the genetic sequence of an organism.
Mutation.
An example of a heterotroph.
Any organism that uses another organism for it's energy source.
L.U.C.A. is an abbreviation for this.
Last Universal Common Ancestor
Nodes on phylogenetic trees represent this.
Common ancestor.
A factor that impacts the location of biomes on Earth.
Climate (temperature, amount of precipitation).
Two types of mutations that are passed to subsequent generations.
1. Beneficial
2. Neutral
An example of an abiotic factor that would affect an ecosystem.
Need one (non-inclusive):
Space, temperature, amount of sunlight, amount of water, quality of soil, wind
This defines a species.
Ability of organisms to interbreed to create fertile offspring.
Cladograms and phylogenetic trees differentiate organisms based on this.
Populations that are limited by a carrying capacity tend to follow this pattern of growth curve.
Logistic curve.
The most accurate piece of evidence to show evolutionary relationships.
Genetic evidence.
The term that describes a specific organism's ability to survive long enough to reproduce.
Fitness.
Name the five aspects of natural selection
Variation
Inheritance
Selection pressures
Differential reproduction
Evolution
Binomial classification features these two taxa. For each taxon, specify how it is capitalized.
Genus and species.
Genus - Capitalized
species - lower case
If the bottom level of an energy pyramid contained 544 kcal of energy, the level above it would receive how much of the energy?
54.4 kcal
Name the five mechanisms of evolution.
Non-random mating.
Small populations.
Mutations.
Gene flow.
Natural selection.
The term that refers to multiple groups of different species of organisms within an ecosystem.
Community.
After a natural disaster, a pioneer species will reinhabit the area. The traits of these initial individuals are most likely to be inherited to future generations. Name this phenomenon.
Founder effect.
The domain to which slime molds belong.
Eukarya.
A change at the predator level of a food chain that impacts the bottom of the food chain.
Trophic cascade.
Populations evolve is one characteristic of all living things. Name the other five.
1) Organized structure (made of cells)
2) Metabolize materials (use energy)
3) Respond to stimuli (environment).
4) Contain genetic material.
5) Grow and develop.
Features in organisms that have a similar function in organisms that evolved separately.
Analogous structures.
