These organisms make their own food using sunlight and have the most energy.
producers
When the Earth's temperature rises, this part of the water cycle speeds up
Evaporation
Adding more people and losing fewer increases this.
population size
These small plants help start new soil on bare rock.
Mosses or lichens
This Renewable resource comes from living things like plants and animals
Biomass
This group breaks down dead stuff and gives nutrients back to the soil. Also having a big impact on the carbon cycle.
Decomposers
What is B?
Condensation
These two things increase the carrying capacity of an ecosystem.
water and habitat
These plants usually grow first after a wildfire.
Grasses
A drawback of wind and solar energy is that they depend on this
weather
If a primary consumers have 7420 kcals of energy available to them in the producers they eat, how many kcals of energy make it into the primary consumer trophic level?
742 Kcals
What are 2 ways that humans increase the amount of carbon dioxide on Earth?
Deforestation, Burning of Fossil Fuels
An invasive species often does this to native plants.
outcompete them
This kind of succession happens when an ecosystem starts from bare rock.
Primary succession
Acid Rain affects this colorful underwater ecosystem by changing the Ph within the ocean.
Coral Reef
Which of the following would be the most likely effect, if there were a sudden increase in the cricket population?
There would be a decrease in the flower population
Animals and Plants do this to release carbon back into the atmosphere
Cellular Respiration
Cutting down a field to build homes causes this to drop.
biodiversity
A mature forest returning after disturbance is an example of this.
Secondary Succession
A population of deer is introduced into a new environment with abundant resources and no predators. Over time, scientists record the size of the population. Which graph best represents how the deer population is likely to change over time in this new environment?
Exponential Growth
The photic zone of an aquatic environment receives ample sunlight, allowing photosynthesis to occur. Based on this information, which type of organism would most likely be found living in the photic zone?
A plant that is photosynthetic
The diagram shows the flow of organic molecules through an ecosystem. What two processes are identified by the labels X and Y?
X; Decomposition
Y; Respiration
A sharp drop in the reindeer population was probably due to this.
Lack of Food/Resources or Hunting
When a population grows too fast and runs out of resources, this often happens next.
Population Decline
What does this graph show us?
The earth's temperature has steadily rising since 1960
