This is an example of: Commesalism occurring between the kudzo and native plants A predator prey relationship between ground plants and kudzu Competition occurring between the native and invasive species Parasitism between kudzu and the native plants 2 / 20 Humans extract resources from nature such as coal, oil, and water.What are some likely problems caused by resource extraction? increased availability to energy resources improved air and water quality increasing amounts of pollution loss of habitats 3 / 20 What happens when humans cut down forests to build shopping malls? The shopping mall reduces the amount of pollution in the area. Plants and animals thrive in the new environment and pollution decreases. New animals species form and plants produce more oxygen. Habitat is altered, plants and animals destroyed, and pollution increases. 4 / 20 What type of succession is shown in the image? Aquatic Succession Community Succession Secondary Succession Primary Succession 5 / 20 A climax community is …. the beginning of a new ecological succession. the fire that will cause destruction. an area that reaches its greatest growing potential. the rocks in a new environment. 6 / 20 What type of succession does the image show? Ecosystem Succession Secondary Succession Primary Succession Aquatic Succession 7 / 20 As you remove resources from an ecosystem, what happens to the population of an organism? It increases then decreases It decreases It increases It stays the same 8 / 20 Any species that occurs outside its native range as a result of deliberate or accidental introduction by humans.

A changing ecosystem that cannot be balanced because of change. A balanced ecosystem that stays the same without any changes. An overall balance between the different parts of an ecosystem although the parts constantly change. 10 / 20 What is the difference between primary and secondary succession? primary has no soil and secondary has soil Primary succession already has soil.

Ecological succession is a process of quick changes in ecosystems. Ecological succession only occurs in water ecosystems. Ecological succession takes place in both land and water ecosystems. Ecological succession in an ecosystem takes place slowly over time. 15 / 20 Why does primary succession take longer to reach climax community? Because primary succession does not have soil Because trees do not perform photosyntheses. Because climax community is in a forrest. Because primary succession already has soil 16 / 20 Which of the following would count as a disruption to an ecosystem? Natural disaster Invasive species All of the Above Change in temperature 17 / 20 Why do the populations of invasive species grow so quickly? They have no food in their new ecosystem. Invasive species have no natural predators. They are prey to many animals. 18 / 20 Pollution can cause harm to the ___________. air water land all of the above 19 / 20 The Final stage of ecological succession is...
