The difference between weather and climate is that climate is:
The average, year-to-year conditions
The day-to-day conditions
Described in terms of months at a time
B and C are both correct
What is the greenhouse effect?
It is a phenomenon where the sun’s rays are absorbed by clouds.
It is a phenomenon that occurs when heat escapes into space.
It is when heat is trapped by gases, then sent back to earth’s surface.
It describes the atmosphere’s composition.
In the woods, there are ducks and mice. They both compete for grasshoppers as the only source of food in that area at that time. The ducks outcompete the mice, and the mice die out in that area. This is an example of:
Neutralism
Commensalism
The competitive exclusion principle
Mutualism
Barnacles are animals that cannot move. In order to get food, they attach to whales and catch any floating plankton in the water. The whale is neither helped nor harmed in the interaction. What type of symbiosis is this?
Mutualism
Commensalism
Parasitism
Neutralism
In the wild, some alligators gets their teeth cleaned by birds. The birds gets their food from the alligators' teeth.
What type of symbiosis is this?
Mutualism
Commensalism
Parasitism
Neutralism
In an ecosystem, there are populations of moose, rabbits, grass, and pine trees. Suddenly, a fire blazes through the area, which kills all of the populations. As the months go on, new species of grass begin to take root. This attracts animals, and eventually the ecosystem is restored.
What type of ecological succession happened?
Primary succession
Secondary succession
Tertiary succession
None of the above
In this photo, what is an abiotic factor?
Deer
Grass
rain
What is this picture describing?
It is describing natural selection.
It is describing direct competition between flamingos and ducks.
It is describing abiotic factors of the tundra.
It is describing the niche of each bird.
Mistletoe grows and spreads on trees, taking their nutrients:
predation
parasitism
mutualism
commensalism
What would happen within a few months after the formation of a volcanic island?
pioneer species would grow
no pioneer species would grow
trees and large plants would grow
rich, organic soil would be present
What would be a good example of a primary consumer?
carnivore
detrivore
decomposer
herbivore
The monkey would be a
decomposer
producer
primary consumer
secondary consumer
Introduced species disrupt ecosystems because they are a/an
Keystone Species
Endemic Species
Invasive Species
Native Species
Mice might grow in population and destroy the community by eating all of the berry bushes if
wolves and snakes were removed from the food web
another predator migrated in to the community
the snake population grew
none of these
These organisms are often not shown in a food chain, but are important for recycling nutrients
producers
decomposers
primary consumers
carnivores
90% of the energy that gets lost as you move up a food pyramid or chain gets lost as
pollution to the environment
heat to the environment
energy for decomposers
gets recycled
What percentage of energy is passed on to the next trophic level?
5%
10%
50%
90%
What has become the most important source of environmental change on Earth?
Climate
Energy
Human Activity
Conservation biology
A biotic or abiotic resource in the environment that causes population size to decrease is a
carrying capacity
logistic growth
limiting factor
growth factor
In this food web, which organism is an omnivore?
grasshopper
mouse
rabbit
squirrel
The image represents four populations in a food chain. Which sequence best represents the transfer of energy between these organisms?
Toads → Predatory insects → Herbivorous insects → Plants
Predatory insects → Herbivorous insects → Plants → Toads
Plants → Herbivorous insects → Toads → Predatory insects
Plants → Herbivorous insects → Predatory insects → Toads
Which graph represents a population that grew and is maintained at the carrying capacity of the ecosystem?
1
2
3
4
Over several years, biologists in a wildlife management area studied changes in the populations of deer and the plants they eat. They created a graph of their data, shown below. Which statement best describes how deer affected the plant population over the course of the study?
The plant population increased dramatically in response to an increase in the deer population.
The deer and plant populations increased and decreased throughout the years, but did not affect each other's population.
When the plant population decreased, this lead to a significant increase in the deer population.
When the deer population increased significantly, the plant population decreased in response
If there is 10,000 kCal of phytoplankton, how much energy is transferred to the Herring?
1,000 kCal
100 kCal
10 kCal
1 kCal
