1. For the following decide if they are density dependent (size matters) or density independent (size doesn’t matter will happen anyway) (Population Growth slideshow 16/17)
a. Weather (snow, rain, drought)
b. Predation
c. Competition
d. Natural disasters (hurricane/tornado/earthquake/floods/drought)
2. Define Carrying capacity (Population Growth slideshow 10-14)
3. HIghlight the factors that would be affected if a population would be near carrying capacity: unlimited
food, limited space/shelter (habitat), unlimited water, disease, predation, competition (Population
Growth slideshow 12/13, 16/17)
4. When given a table of the following numbers of a species, determine the carrying capacity: 100, 97,
100, 101, 99, 100, 98. (Population Growth slideshow 12)
5. Briefly describe a predatory/prey boom bust graph. (Population Growth slideshow 18)
6. For the following decide if they are abiotic (non living) or biotic (living): (ecology slide show slide 3)
e. Food f. Disease
g. Human activities (deforestation, dams)
NOTE: Human activities are anything involving humans and can include use of pesticides, herbicides, our
contribution to climate change, habitat loss and destruction, poaching/hunting, etc.
a. Bacteria
b. pH level
c. fungus
d. plants
e. oxygen availability
f. Sunlight
g. water
h. animals/parasites/predators i. pollution
7. Be able to apply the 10% rule when given a pyramid or a food chain/web (ecology slideshow 20-23) Remember just move the decimal point 1 time for each step. The other 90% of energy is lost as heat energy.
In the following food chain what amount of energy does the snake have if the seed starts with 29345 kcal of energy?
Seed→mouse→snake→ hawk.
Remember the further away from the plant (autotroph) the less energy you have. Bacteria feed on anything that dies.
8. What type of energy is lost during food chains/webs? (HInt 10% rule, plants give energy to animals then they give energy to bacteria when they die (bodies decomposed))

1) DI: a,d,g. DD:b,c,e,f. 2) K is a constant equal to the population size at the equilibrium. 3) 2,4,5,6. 4) 100. 5) Prey population size is followed by predator population size. 6) B: a,c,d,h. A: b,e,f,g,i. 7) 293.45 kcal. 8) caloric energy.

These are limiting factors that affect the carrying capacity.

a. Weather (snow, rain, drought) → Density-independent

b. Predation → Density-dependent, DD

c. Competition → Density-dependent, DD

d. Natural disasters → Density-independent, DI

e. Food availability → Density-dependent, DD

f. Disease → Density-dependent, DD

g. Human activities (deforestation, dams) → Density-independent, DI

Carrying capacity (K) is the maximum point at which the environment can support a growing population. It is a constant equal to the size of the population (N) at the equilibrium point when the natality rate and the mortality rate get equal to each other.

3)

4) 100 is the number of individuals in a species that equals the carrying capacity.

When a prey lives in the ideal environment with no predators, it shows an exponential growth rate.

Prey can grow, develop, and reproduce, increasing its population size.

But when predators appear, the more available items, the more predator there will be.

The predator population increase in size, decreasing the prey populations size. So there are fewer available items to prey on.

The prey population also affects the predator population. The predator depends on the prey density. The more predators there are, the fewer prey there will be left.

The predator population decreases exponentially due to the item's lack. The predation rate depends on density as well as natality and mortality rates.

Predatory/prey graph,

The graph shows the variation in population size of predators are preys with time. For a better understanding look at the attached files.

1. prey population increases in size → red line

2. predator population increases in size → green line

3. prey population decreases in size → red line

4. predator population decreases in size → green line

The ecosystem is composed of living and non-living things that interact and depend on each other.

a. Bacteria → Biotic, B

b. pH level  → Abiotic, A

c. fungus  → Biotic, B

d. plants  → Biotic, B

e. oxygen availability → Abiotic, A

f. Sunlight → Abiotic, A

g. water → Abiotic, A

h. animals/parasites/predators  → Biotic, B

i. pollution → Abiotic, A

From the energy that reaches the earth's surface, only 0.1 or 1% is taken by autotroph organisms. This small percentage of energy flows through all organisms in the ecosystem until it dissipates in the environment.

The 10% rule states that only about 10% of the energy stored as biomass at one trophic level, ends up as biomass at the next trophic level.

The progressive reduction of energy determines the number of trophic levels (4 or 5).

Seed → 29345 kcal of energy

⇒ 10% of 29345 kcal is 2934.5

The mouse gets  2934.5 kcal of energy

⇒ 10% of 2934.5 kcal is 293.45

The snake gets  293.45 kcal of energy

⇒ 10% of 293.45 kcal is 29.345

The hawk get 29.345 kcal of energy.

According to these calculations, the snake have 293.45 kcal of energy.

Producers receive luminous energy from the sun, and they store 1% of it.

Consumers along the trophic web receive 10% of chemical energy from the direct anterior link. The remaining energy is lost as caloric energy.

The correct answer is caloric energy.

Abe knew from his anatomy class that there are three different kinds of muscle tissue in the body. He knew lifting weights would help build the skeletal muscle and that running was good for cardiac muscle health. He was surprised to find out that his blood vessels had smooth muscle, so his exercise regimen was actually benefitting all the muscle types of his body. Correctly sort each of the characteristics into the appropriate category.

White-tailed deer are native to both North and South America. They can be found in many areas of the United States. They can adapt to a wide range of habitats and eat a large variety of plants, including leaves, fruit, bark from sapling trees, flowers, corn, and even poison ivy.
