Select True or False (T/F)
17. Endemic species are those that are typically found in a given region.
18. Humans are a tertiary consumers because they eat animal tissues.
19. In many ecosystems, the abundance of a species may be determined by a species that feeds on it. This is an example of top-down control.
20. It takes about 10x more energy to grow a cow than to grow wheat.
21. Many insects are food for birds. Since both of these are animals, changes in climate will have minimal effect because it would affect both organisms in a similar manner.
22. Much of the energy that is available in a diet is lost to inefficiencies in the form of heat.
23. Net primary productivity (NPP) is the total amount of chemical energy captured by primary producers.
24. Resilience of a community is a measure of how stable it remains in terms of biodiversity.
25. Since evolution acts at the level of gene frequencies, biodiversity is best assessed at the level of gene frequencies.
26. The most important species to conserve are those that represent unique lineages.
27. The recent increases in anthropogenic activities, including those that result in climate change, are likely to lead to the first mass extinction event in the history of the planet.
28. Wildlife corridors are strips of habitat connecting two reserves which permits animals to move between at diminished risk.
Explanation / Answer
17: True:Endemic species are plants and animals that exist only in one geographic region.Species can be endemic to large or small areas of the earth: some are endemic to a particular continent, some to part of a continent, and others to a single island.
18 Dependable on book or what reference to using. Humans are omnivores. In some references omnivores are synonymous to tertiary consumers and in some there are secondary
20 True because Cattle can only integrate 10% of their food into biomass.
