Question

short answer: use the diagram on the right to answer questions 13-16. 13. what is this type of diagram called? 14. what does each bar on the diagram represent from bottom to top? 15. if this diagram indicated biomass, which two trophic levels show the greatest change in biomass? 16. if this diagram indicated energy transfer, between which two trophic levels is the smallest amount of energy true or false (17-20). indicate if the statement is true (t) or false (f). 17. burning fossil fuels worries those who think that global warming is a problem because it is a human - made way of adding more carbon dioxide to the air. 18. the maximum number of organisms of a particular species that can be supported by an environment is called population density. 19. the main types of terrestrial biomes include tropical rainforests, savannas, chaparrals, deserts, temperate grasslands, temperate deciduous forests, tundras, and tiagas. 20. competitive exclusion is the term used to describe what happens when two populations of different species compete for the same food source or their niches overlap.

Explanation:

1. The diagram is a pyramid - shaped one often used in ecology to represent trophic levels, so it is a trophic pyramid.
2. In a trophic pyramid, bars from bottom - to - top represent successive trophic levels starting from producers at the bottom and moving up to top - level consumers.
3. Usually, the greatest change in biomass occurs between the producer level (bottom) and the primary consumer level just above it as energy transfer is inefficient.
4. Energy transfer is most inefficient between the highest trophic levels, so the smallest amount of energy transfer is between the second - highest and the highest trophic levels.
5. Burning fossil fuels releases carbon dioxide, a greenhouse gas, contributing to global warming, so the statement is true.
6. The maximum number of organisms of a particular species that can be supported by an environment is called the carrying capacity, not population density, so the statement is false.
7. These are well - known main types of terrestrial biomes, so the statement is true.
8. Competitive exclusion describes the situation when two species compete for the same resources and one outcompetes the other, so the statement is true.
