Types of Succession
Wildfires
Secondary Succession
Venom production in snakes, camels conserving water in the desert, skunks producing defensive scent, and cold-active proteins in Arctic fish blood.
Physiological Adaptations
Ocean currents influence global weather patterns. Which statement describes an effect ocean currents have on regional temperatures?
A Ocean currents moving water from the equator toward the poles can increase temperatures near the poles.
B Ocean currents moving water from the poles toward the equator can increase temperatures near the
equator.
C Ocean currents moving water from the equator toward the poles can decrease temperatures near the poles.
D Ocean currents moving water from the equator toward the poles can increase temperatures near the equator.
A
Scientists are comparing two ecosystems and want to determine which ecosystem is most likely to recover from a natural disaster.
Which method should the scientists use to BEST develop a claim about the stability of these ecosystems?
A Count the number of plant species
B Count the number of animals
C Count the total number of organisms
D Count the total number of different species
What is D
Which one takes longer?
What is natural selection?
Lava Flows
Primary Succession
A turtle's shell for protection, bird wings for flight, a giraffe’s long neck, or a cat's tapetum lucidum for night vision.
Structural Adaptations
Artificial reefs made of concrete or limestone are put in the ocean to provide a habitat for marine animals.
Which statement BEST describes how the stability and value of a natural reef compare to those of an artificial
reef?
A A natural reef is less stable and provides lower-quality habitat.
B A natural reef is more stable but provides lower-quality habitat.
C A natural reef is less stable but provides higher-quality habitat.
D A natural reef is more stable and provides higher-quality habitat.
C
A group of organisms that can reproduce together.
Species
Another term (2 words) for artificial selection.
What is selective breeding?
Sand Dunes
Primary successions
Birds migrating, animals hunting in packs, nocturnal activity to avoid heat, or specific mating calls.
Behavioral Adaptations
The occurrence of an organism, trait, or gene in more than one form
Variation
Living and nonliving things interacting in an area.
Ecosystem
What is the difference?
Natural selection is where nature decides which animals breed. Artificial selection is where people decide which animals breed.
Abandoned Farmland
Secondary Succession
Entering a state of dormancy to conserve energy during harsh winters.
Types of Alleles one will always show up and one will only show up if two are present
Dominate and Recessive
The movement of energy through organisms.
Food Chain or Food Web
Of the following, what is not an example of natural selection:
1. 2 animals breed together in a zoo on their own
2. 2 animals with likable traits breed on their own
3. 2 animals with likable traits get bred by people that chose those animals
Number 3: 2 animals with likable traits get bred by people that chose those animals
Glacial Retreat
Primary Succession
A polar bear surviving in the harsh cold and a black bear dying in the same environment is an example of what
natural selection/survival of the fittest
A plant species is found where a recent volcanic eruption has covered the landscape with rock. The list describes some characteristics of the plant species:
Which statement MOST LIKELY describes the role of this species in the ecological succession of the area?
A This species will continue to grow, attracting large predators to the area.
B This species will become well established in the environment before using up all the resources.
c This species will change the environment, allowing other plants to survive.
d This species will move out of the area after new types of plants start to grow in the area.
c
The likelyhood that an ecosystem is sustainable
High Biodiversity
Is the following an example of artificial selection or natural selection:
Three-spined stickleback fish populations are found in streams, lakes, and the coastal areas of oceans of the United States. Stickleback populations that live only in lakes and streams have less armor than the populations that mostly live in the oceans.
