A population has unlimited resources. What type of growth curve will this population experience?
(a)
Which bets represents carrying capacity?
How much weight you can squat at the gym
a species average population size in a particular area.
What percent of energy moves up the trophic levels?
(a)
Is the following factor a density-dependent or density-independent factor? Disease
Density-independent
Density-dependent
Ecology study is most like which of these...
the carrying capacity of muscles
how trees transport water
the blood flow of an earth worm
the interactions between populations of rabbits and coyotes
A group of monkeys use jungle trees to get food and live in. What would happen if most of the trees got chopped down?
The monkeys will have larger immigration into that jungle
the monkeys will dig dens underground and start eating worms
the monkey population will lack resources and begin to decrease in population size.
The monkeys will have more babies to compensate
Is the following density-independent or density-dependent? Hurricane
density-independent
density- dependent
The tick population on a dog is monitored for 6 weeks after adding tick medicine. Which type of growth curve is being demonstrated ?
Exponential growth curve
Logistic growth curve
Is the following factor density-dependent or independent? Food
density-independent
density-dependent
This diagram represents for trophic levels in an ecosystem. which statement best explains the energy transfer
About 10% of the energy at one trophic level gets transferred to the next trophic level.
Birds have the most amount of energy from the other levels.
Most of the energy is transferred to and from the grass because it doesn't have to move to find food.
The energy floe through all the levels and then back to the producers.
Is the following factor abiotic or biotic? Sharks
biotic
abiotic
If a sub-population of species has a genetic advantage what is most likely to occur?
That species will increase
that species will decrease
Is the following a biotic or abiotic factor? Roses
Abiotic
Biotic
Select which one is from SMALLEST to LARGEST
community, individual, population, ecosystem, biome, biosphere
individual, population, community, ecosystem, biome, biosphere
individual, community, population, ecosystem, biosphere, biome
population, individual, community, ecosystem, biome, biosphere
Is the following factor density-independent or density-dependent? Predators
density-independent
density-dependent
What impacts do biodiversity have on a community? (select all that apply)
Biodiversity enables communities to withstand changes
biodiversity enables individual species to survive
biodiversity allows multiple advantages traits to remain available for selection
biodiversity stabilizes the populations of species in the community
All of the above
which statement is true about Earth's carrying capacity?
the population growth makes the carrying capacity grow
technology has increased it
it is infinite
it reached maximum capacity last year.
A population has unlimited resources. What type of growth curve will this population experience?
(a)
A population of wolves lives in a forest. They hunt buffalo, deer, rabbits, and other prey. If the wolf population increases, which of the following will occur?
More wolves will be born, and all of them will survive to adulthood
A natural disaster acts to decrease the wolf population by at least 50%
A decrease in the competition will increase the growth rate of the population
Competition for territory and other resources acts to slow the growth rate of the population.
This image is modeling organisms in an ecosystem. Which scenario best explains this pyramid's shape?
A dead dear feeds many foxes and wolves
A squirrel who gathers lots of nuts for winter
Grass in a field that feeds many small animals
A tree that provides food for thousands of insects
Is the following factor biotic or abiotic ? Wind
Abiotic
Biotic
Which human activities can protect the biodiversity of an ecosystem?
clear more forested areas to put housing
urbanization
use more pesticides
use and create nature reserves/ parks tp provide more natural habitats
This image is best described by which statement?
effects of reduced competition between types of plant life
ecological succession from bare rock to a stable ecosystem.
effect of human intervention on a stable ecosystem
evolution of mosses to trees over 200 years
The graph describes the population of dandelions s in a field over the course of one summer. Which statement best describes the growth of the dandelions?
Linear growth occurs because the field provides abundant but limited resources during the summer.
Logistic growth occurs because the field provides unlimited resources during the summer.
Exponential growth occurs because the field provides unlimited resources during the summer.
Fluctuating growth patterns occur because the population reached the carrying capacity of the field during the summer.
The carrying capacity for adult frogs in a wetlands ecosystem is 1000 individuals. The frogs eat flies and other small animals, and they are prey for raccoons, snakes, and large birds. Which event will most likely happen if an additional 200 adult frogs immigrated to the ecosystem?
The carrying capacity for frogs would increase by 200 frogs.
The frog population would experience a pattern of exponential growth.
About 200 adult frogs would die because of lack of resources, or by predation.
As a population approaches carrying capacity, which of the following is predicted by the logistic growth equation?
the growth rate will approach 0
the population will increase exponentially
the carrying capacity of the environment will increase
A food web shows feeding relationships in an ecosystem. In this food web, what is represented by the chains of arrows from the grass to the fox?
the one-way flow of energy through the ecosystem
the one-way flow of matter through the ecosystem
the conservation of energy in the ecosystem
the removal of energy from the ecosystem
Density-Dependent best fits which description
growth rates are regulated by the seasonal floods
growth rates are affected by the density of the population
growth rates are increased dramatically.
