Characteristics of Life
Which one is NOT a Characteristics of Life?
- Metabolism - Reproduction
- Autotroph - Response to stimuli
- Growth - Evolution
Answer: Autotroph is not a Characteristics of Life
Characteristics of Life:
Metabolism, Cells, Growth, Development, Reproduction, Homeostasis, Response to stimuli, and Evolution
Which is NOT a biogeochemical cycle?
- Carbon Cycle
- Hydrophobic Cycle
- Hydrologic Cycle
- Nitrogen Cycle
Answer: Hydrophobic Cycle
Biogeochemical cycles are
- Carbon Cycle
- Oxygen Cycle
- Hydrologic Cycle
- Nitrogen Cycle
Label if each example is an autotroph or a heterotroph:
1. Decomposer
2. Secondary Consumer
3. Producer
1. Decomposer - heterotroph - eats and break down other organisms
2. Secondary Consumer - heterotrophs - eats other organisms
3. Producer - Autotroph - turns inorganic material into food
If owls eat hawks, would an arrow in a food model of these two animals point at the owl or the hawk?
Answer: the owl
Why: arrows show where energy goes, so if the owl eats and gets the energy from the hawk, the arrow will point at the predator
What happens to the level of toxins as you go up the food chain?
The level of toxins will increase in organisms as you go up the food chain due to the 10% Rule of Energy
Which Characteristics of Life is defined as "maintaining a balance in the body"?
Answer: Homeostasis
Homeo - home or baseline
Stasis - state of
Ex: a fever to kill bacteria, sweat to cool down
Do the matter that make up the Biogeochemical Cycle recycle through the environment or does it move in one direction, getting smaller?
Answer: Matter in this cycles will RECYCLE through the ecosystem.
Tip: Energy is what moves in one direction, getting smaller through the ecosystem.
1. Eco- means what?
2. -ology means what?
3. Define Ecology
1. Eco = environment (but it actually means "house")
2. -ology = the study of
3. Ecology is the study of the (house) environment
Do arrows in a food model represent the movement of matter (food particles) or does it represent energy?
What happens to the level of toxins as you go up the food web?
The level of toxins will increase in organisms as you go up the food chain due to the 10% Rule of Energy
Match the example to their Characteristics of Life (a number with a letter):
1. Cell organization
2. Development
3. Metabolism
A. Autotroph: makes their own food from inorganic material
B. Stages of a frog: egg, tadpole, then adult frog
C. Unicellular: made of one cell like a bacteria
Answer:
1-C: Cell organization - Unicellular
2-A: Development - Stages of frog
3-B: Metabolism - Autotroph
What is the difference between evaporation and transpiration in the hydrologic cycle?
Answer:
Evaporation is water going from liquid to a gas FROM BODIES OF WATER (lake, rivers)
Transpiration is water going from liquid to a gas FROM BIOTIC organisms (plants - sweat, human - sweat)
Define a population:
It is all of __________ in ___ given area
Answer: Population is all of the organisms of one species in one/single given area
Food web can have multiple food sources to the next: multiple paths or energy to travel.
What is the 10% Energy Rule? Use 10% in your answer.
The 10% Energy Rule is a rule that states that prey will only pass on 10% of the energy they put into their bodies to their predator
Label if each example is a biotic organism or an abiotic object:
1. Rock
2. Plankton
3. Virus
4. Bacteria
1. Rock - abiotic - missing all characteristics of life
2. Plankton (animal) - biotic - has all characteristics of life
3. Virus - abiotic - missing some characteristics of life
4. Bacteria- biotic - has all characteristics of life
Match the term to the definition below:
1. Denitrification
2. Nitrogen fixation
A. Turns unusable Nitrogen gas to a usable solid form
B. Turns usual Nitrogen solids into an unusable gas form
1-B: Denitrification: destroy so turn usable Nitrogen to unusable Nitrogen
2-A: Nitrogen fixation: turns unusable Nitrogen to a usable Nitrogen
Match the term to their definition:
1. Community
2. Ecosystem
3. Population
A. All of the biotic things in a habitat
B. All of the individuals of one species in a habitat
C. All of the living and nonliving things of one habitat
1-A. Community - All of the biotic things in a habitat
2-C. Ecosystem - All of the living and nonliving things of one habitat
3-B. Population - All of the individuals of one species in a habitat
If the primary producer is plankton (animal) would the secondary consumer, a crab (animal), be:
1. an autotroph or heterotroph
2. carnivore, herbivore, omnivore, or detrivore
Crab (animal) eating plankton (animal) would make crabs:
1. heterotrophs
2. carnivores
There are more cows than humans because the 10% Energy Rule says predators only get 10% of the prey's energy. So predators have to eat multiple prey in order to be "full" (of energy).
Chemical reactions in the body are classified as which characteristics of life?
Answer: Metabolism
Breaking down food is a chemical reaction. Using food as energy is a chemical reaction.
What organism does the whole Nitrogen cycle? (does nitrogen fixation and denitrification for the environment)
Match the term to their definition:
1. Community
2. Ecosystem
3. Population
A. All of the trees in Worthington
B. All of the trees and birds in Worthington
C. All of the trees, birds, and light poles in Worthington
1-B. Community: All of the trees and birds in Worthington
2-C. Ecosystem: All of the trees, birds, and light poles in Worthington
3-A. Population: All of the trees in Worthington
If the primary producer is sunflower seeds (plant) would the tertiary consumer, a hawk (animal), who can eat both the producer and secondary consumer be:
1. an autotroph or heterotroph
2. carnivore, herbivore, omnivore, or detrivore
If hawk (tertiary consumer) can eat primary consumer (plant) and secondary consumer (animal) then a hawk is
1. Heterotroph
2. omnivore
Make a food web for:
The plankton gets energy from the sun
Whales and crabs eat plankton
Whales eat crabs and plankton
Sponge also eats plankton
