Part A Begin by selecting a freshwater or marine aquatic ecosystem as a model for your food web. Be specific.
Choose a specific lake. Or, if you choose an ocean ecosystem, identify its geographical area and depth.
Keep in mind that deep-sea organisms live in a completely different environment than surface aquatic
organisms.
Next, conduct research on the following conditions in the ecosystem you chose. They influence the types
of organisms that can live there.
geographical features
temperature
depth/light availability
salinity
• PH
• unique features that contribute to the ecosystem, such as other bodies of water that connect to it,
unusual chemistry, and climate
Using the information you gathered, write a paragraph that describes conditions in the ecosystem.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.

One reason scientists are trying to develop fuel sources from corn and sugar is because these sources are renewable fossil fuels are being depleted these crops can be widely grown all of the above
