Global warming has been hypothesized to cause many plants to flower earlier. If bees and other pollinators begin the search for food earlier in response to this, this would represent ________ within the community.
Coevolution
If the climate warms significantly, glaciers may melt, exposing underlying rock. This may lead to ________ in the community.
Primary Succession
________ capture solar energy and use photosynthesis to produce sugars.
Producers
Fish that eat zooplankton would be considered ________.
Secondary consumers
Which of the following is an example of resource partitioning?
Two species of birds forage together, with one eating insects on tree trunks while the other eats insects in the outer branches.
Which of the following is true about top predators? a. They are likely to be keystone species b. Their removal increases biodiversity. c. They are likely to be herbivores. d. They are likely to be producers. e. They include bacteria and fungi.
a. They are likely to be keystone species
Zebra mussels ________.
are an invasive exotic species that clogs water intake pipes at factories, power plants, and wastewater treatment facilities
If global climate change results in an area of temperate grassland receiving less rainfall and higher temperatures, it will ________
begin to support more desert species
Based on the scenario from question 21, answer the following question. Global warming has been hypothesized to cause many plants to flower earlier. If bees and other pollinators begin the search for food earlier in response to this, this would represent ________ within the community.
coevolution
By definition, parasites ________ their host.
feed on and harm
Read the following scenario and answer the question(s) below. Human activities, including fossil fuel combustion, farming, and deforestation, are known to increase atmospheric levels of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. Measurable warming of Earth due to these gases can alter ecosystem dynamics. In addition to the direct climatic effects on organisms within biomes, warming can melt permafrost in the tundra and increase precipitation in arctic areas. Global warming also can increase sea surface temperatures, melting sea ice in the Arctic and increasing the intensity of hurricanes in temperate and tropical coastal areas. Within communities, climatic change can shift interdependent species "out-of-sync," potentially causing indirect loss of species. The relationship between caterpillars and flowering plants is best described as ________.
herbivory
Based on the scenario from question 21, answer the following Which of the following might be first to populate an area after glaciers melt in response to global climate change?
lichesn
Based on the scenario from question 21, answer the following question. If the climate warms significantly, glaciers may melt, exposing underlying rock. This may lead to ________ in the community.
primary succession
Some models of climate change for North America predict that the grassland regions of the prairie states will become warmer and drier. This would result in ________.
the need to develop varieties of agricultural crops that tolerate desert conditions
The energy content and biomass of ________ is lowest in any terrestrial food web.
top carnivores
What terrestrial biome has the most biodiversity?
tropical rainforest
