This evidence for evolution shows change in species over time, speciation, and extinction. It is the preserved remains or impressions of ancient life.
What is fossils.

In England peppered moths went from being usually light colored to being usually dark colored. What environmental change led to this evolution?
What is the darkening of the trees by soot from human industry.
100
The number of species.
What is species richness
100
The study of the interactions between living and nonliving things.
What is ecology.
100
The 'bio' in biology means what?
What is life.
200
Different species have parts of their body that do different things but develop from the same part of the embryo and have developed from a common ancestor. An example is the hand of a human and the wing of a bat.
What is a homologous structure.
200
A trait that helps an organism survive and reproduce.
What is an adaptation.
200
How equal the number of individuals is between species in a biological community.
What is evenness.
200
A system including the living things present and the nonliving things present. E.g. a forest with trees, deer, rabbits, rocks and air.
What is an ecosystem.
200
The x-variable in a graph is also known as the ___________ variable.
What is the independent variable.
300
A change in how common a trait is in a population over time.
What is evolution.
300
A change in the DNA that can benefit an organism, harm it, or have no effect on its survival.
What is a mutation.
300
These two ecosystems are among the most biodiverse on Earth. One ecosystem is found on land and the other is found in the ocean.
What are tropical rainforests and coral reefs.
300
The first five levels of ecological organization beginning with the individual.
What are the individual, the population, community, ecosystem, and biome.
300
If you were graphing the change in deer population over a 10 year timespan, what would be your dependent variable?
What is deer population.
400
Early in the development of an organism these are similar to each other but then develop into very different adult organisms. By comparing these early stages we can see organisms share a common ancestor.
What are embryos.
400
Whales have only been very large for the past few millions of years. What environmental change most led to their increase in size?
What is warming of the planet, melting of ice carrying nutrients, leading to patches of food far apart from each other.
400
Which community had a higher species evenness and how can you tell?_______________ Community 1 Species A: 30 Species B: 46 Species C: 80 Species D: 14 _________________ Community 2 Species A: 25 Species B: 104 Species C: 10 Species D: 20
What is Community 1 because the number of individuals of each species is more similar while in Community 2 only Species B is very common.
400
Biomes on land are mostly defined these two variables. (A variable is just something that can be different, in other words, how do the biomes differ, what makes them differ).
What are temperature and precipitation.
400
Two traits that unite all primates.
What are finger, toes, binocular vision, a well developed cerebrum.
500
In hospitals we can see evolution taking place. When most bacteria are killed by antibiotics only the strongest bacteria are left behind causing a threat to human health. This is known as the evolution of what trait?
What is antibiotic resistance.
500
What environmental change most led to the evolution of horses from being small and having 5 toes to being large and having a single toe (hoof)?
What is the warming and drying of the environment leading to forest being replaced by grassland.
500
Two factors that lead to higher biodiversity in ecosystems.
What are habitat complexity, medium levels of competition, medium levels of disturbance.
500
The top of an energy pyramid is smaller than the bottom. E.g. there are fewer foxes than dandelion plants. What accounts for this difference?
What is the loss of energy at each trophic level as heat.
500
The difference between a photosynthetic and a chemosynthetic organism with an example of each.
What is photosynthetic organisms such as plants and cyanobacteria use light to make food while chemosynthetic organisms like the bacteria around deep sea vents use chemical compounds as a source of energy.
