Ms . Sue, Please check my work on Wednesday, July 20, 2011 at 9:34am. Thank you.
Writeacher already checked your work.
1. The correct answer is c) conservation. When people decide to use resources in the environment carefully, they are practicing conservation. To understand this concept, you can think of conservation as the responsible use and preservation of natural resources. Conservation involves using resources wisely, protecting habitats, and minimizing waste.
2. The correct answer is d) maintaining and restoring the environment. Preservation of resources means that we maintain and restore the environment for future generations. This involves using resources with minimum waste and ensuring that our actions are sustainable.
3. The correct answer is d) the need for conservation. The recent energy shortage indicates the need for conservation. Conservation helps us use resources more efficiently and reduces the strain on limited supplies. It is a response to the growing demand for energy and the recognition that we need to protect and preserve our resources.
4. The correct answer is b) grasslands. The animal community described in the question (gophers, jack rabbits, prairie dogs, and antelopes) and the absence of forests during the summer growing season point to the biome being grasslands. Grasslands are characterized by extensive open areas covered with grasses and are found in various parts of the world.
5. The correct answer is e) none of the above. The continental shelf refers to the underwater extension of a continent and is typically broader and shallower than the adjacent deep-sea areas. None of the given options accurately describe the dimensions of a continental shelf.
6. The correct answer is a) intertidal zone. The intertidal zone is the area on land that is covered during high tide but exposed during low tide. It is a dynamic and challenging environment where organisms must adapt to changing conditions due to the ebb and flow of the tides.
7. The correct answer depends on the current information you have. As an AI, I am unable to provide real-time data. However, states with large areas of wilderness that people can visit to experience a natural environment include California (a), Alaska, Montana, Wyoming, and Utah, among others.
8. The correct answer is b) Scavengers. The benthic zone is the lowest level of a body of water, such as the bottom of a lake or ocean. It is home to scavengers, which are organisms that feed on dead or decaying matter.
9. The correct answer is d) on or under land. Most organisms on our planet live on or under land. While there are abundant life forms in water, the majority of species inhabit terrestrial environments such as forests, deserts, grasslands, and tundra.
10. The correct answer is a) large forest fires caused by lightning. While forest fires caused by lightning can have a negative impact on the environment, they are considered a natural occurrence and not necessarily a result of man polluting his environment. On the other hand, options b), c), d), and e) all involve human activities that contribute to pollution and environmental degradation.
