Life
What are abiotic and biotic factors?
Abiotic are non-living parts of an ecosystem. Biotic are living or once-living parts of an ecosystem.
Which type of succession occurs faster?
Secondary succession because it already has established soil.
What are macromolecules?
Large molecules composed of smaller ones that are linked together.
What is the chemical equation for photosynthesis?
6 CO2+6 H2O-----> C6 H12 O6
What are the four types of consumers (heterotrophs)?
Carnivore, omnivore, herbivore, and decomposers.
Human impact can change an ecosystem, what are 4 different changes humans cause.
Water pollution, agricultural, industry, and municipal.
What are the elements that makeup proteins and what are 2 functions of a protein?
CHON- carbon, hydrogen, oxygen and nitrogen
Some functions are: maintain shapes of cells, majority of muscle tissue, some proteins are antibodies, and they can carry materials through the body.
What items are recycled through the water cycle?
water, nitrogen, carbon, and phosphorus
When birthrates and death rates become stable, the population levels off at __________.
carrying capacity. This growth is also called logistic growth.
What are the 3 types of symbiotic relationships and what do they mean?
1. Parasitism- one benefits, other is harmed
2. Mutualisim- both benifit
3. Commensalism- One benefits, other is unaffected
Which 2 macromolecules only have the elements carbon, hydrogen, and oxygen (CHO)?
Carbohydrates and lipids (fats).
Bacteria, lichen, and weather break down the rock to soil
When a population size has no limiting resources what is this growth called?
Exponential growth
What is the main difference between secondary and primary succession?
Primary succession starts with rock, while secondary succession already has established soil.
What macromolecule is CHONP?
Nucleic acid (carbon, hydrogen, oxygen, nitrogen, and phosphorus).
What's the definition of limiting factors?
Limits the growth of a population
In two ways how do we define life?
1. Have cells or single-celled
2. Uses energy
3. Grows and develop
4. Reproduce
What are some examples of extreme changes?
Volcanoes, earthquakes, tsunamis, glaciers, etc.
What are the four types of macromolecules?
Carbohydrates, lipids, proteins, and nucleic acid.
What is one function of nucleic acids?
It contains information needed for cells to make proteins.
