Growth and Population
What is a density dependent factor?
Resources that are limited because the rate at which they become depleted depends on the density of the population that uses them. Examples include: Food, water, shelter
Where does cellular respiration take place?
Mitochondria
This is an animal or plant that primarily eats the flesh of other animals for energy and nutrition.
Carnivore
What structure is it called when the body parts in different species that have a similar structure and origin by may have different functions.
Homologous Structures
TRUE OR FALSE
Human arm, Cat leg, Whale flipper are examples of analogous structures.
FALSE
This is an example of Homologous Structures
What is the maximum population size of a species that a particular environment can normally and consistently support in terms of resources?
Carrying Capacity
What are the reactants of cellular respiration?
Glucose (Sugar) and Oxygen
This recycles nutrients from dead organisms back into the soil to support producers.
Decomposers
What are fossils of organisms that show characteristics of both an ancestor species and a descendant species?
Transitional Fossils
What is artificial selection?
Where humans intentionally breed organisms for a specific trait
What are at least 2 density-independent factors?
Weather Events
Natural disasters
Human Activity
Climate Change
This is a type of ANAEROBIC RESPIRATION that occurs when oxygen is not available to cells, or when cells need to produce ATP quickly, such as in muscle cells during intense exercise.
Lactic acid fermentation
What does the Pyramid of Numbers measure?
Shows the number of individual organisms at each trophic level.
What is Adaptation?
Adaptation is a feature that helps a species survive in its environment.
Put this in the correct order (food chain):
-Carnivore
-Herbivore
-Producer
PRODUCER-->HERBIVORE-->CARNIVORE
Put this in the correct order from smallest to largest:
Biosphere
Community
Population
Biome
Ecosystem
Individual
Individual → Population → Community → Ecosystem → Biome → Biosphere
What is the equation for Photosynthesis?
Carbon Dioxide + Water + Sunlight Energy --> Glucose + Oxygen
Carbon is able to bond to how many different elements at once?
Carbon can make 4 bonds
Explain Vestigial Organs/Structures in your own words.
Body parts (structures) that have lost their original function through evolution. They are remnants of features that were useful to an ancestor but are no longer necessary.
What type of growth is when a population size increases exponentially over a short period of time?
Exponential Growth
Define the three types of symbiosis
Mutualism: Both benefit
Commensalism: One benefits, other unaffected
Parasitism: One benefits, one harmed
How are photosynthesis and cellular respiration related in the carbon cycle?
Photosynthesis uses the products of cellular respiration, and cellular respiration uses the products of photosynthesis
GRASS BUNNY SNAKE HAWK
Make me a pyramid showing these organisms and label the trophic levels with the organisms names above and to the right side of each box, indicate how much energy (PERCENTAGE) is available at each trophic level.
HAWK 0.1%
SNAKE 1%
BUNNY 10%
GRASS 100%
What is the main difference between Artificial Selection and Natural Selection?
Artificial selection is driven by human choice. Humans select the organisms with the traits they want to reproduce, controlling which traits get passed onto future generations. Natural selection, on the other hand, is driven by environmental factors. In nature, organisms with traits that help them survive and reproduce in their environment are more likely to pass those traits on, without human interference.
What is the theory of common ancestry?
popularized by Charles Darwin, proposes that all living organisms on Earth share a single universal common ancestor (UCA) from which they have all descended, a concept forming the foundation of modern evolutionary biology
