The Flow of Energy: Primary Production

select the correct statement about photosynthesis by primary producers

Primary producers convert an source of energy e. B It receives a greater amount of solar energy per unit area. D rapid eutrophication of streams and lakes. All materials © the Regents of the University of Michigan unless noted otherwise. It is unicellular and heterotrophic.

D Matter can be converted into energy; energy cannot be converted into matter. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by implied by the arrow into a sugar molecule and six oxygen molecules, the products. Which one of the following best describes the base of a pyramid of net production? Food chain always start with producer, which of the following is an exceptional to the given statement. Clearly, because of all of the energy costs of hares engaged in normal metabolic activities, the energy available to foxes is much less than the energy available to hares. For example, grasslands can have a relatively high rate of primary production occurring during a brief growing season, yet the standing crop biomass is never very great.

For example, If hares consumed 1000 kcal of plant energy, they might only be able to form 100 kcal of new hare tissue. B Collect the clippings and burn them. A Obesity B Artheros cerosis C Inadcquale of O2 supply D Hypertension 87. It helps in absorbtion of phosphorous? B observe Antarctic Ocean productivity and compare that to other areas. As was discussed in detail in a previous lecture, the plant requires sunlight, carbon dioxide, water, and nutrients, and through photosynthesis the plant produces reduced carbon compounds and oxygen. It is simply a feeding level, as often represented in a food chain or food web.

She can rub her seeds with sand paper prior to planting. A Molecules move through all ecosystems at the same constant rate, as the laws of physics would predict. B The total energy content of the seaweeds is lower than that of the seals. . For other ecosystems such as the temperate forest, the pyramid of numbers might be inverted: for instance, if a forest's plant community was composed of only a handful of very large trees, and yet there were many millions of insect grazers which ate the plant material. In material cycle which of the following is last acceptor of material? The table gives a low estimate. Now consider the following simple example.

Many reactions occur, but the overall chemical reaction for photosynthesis is: In a plant, the carbon dioxide enters via leaf stomates by. A Primary producers B Secondary consumer. Primary producers ares at the lowest , and are the reasons why Earth is sustainable for life to this day. They include consumers of any organism, in any form: plants, animals, microbes, even dead tissue. Select the correct statement about photosynthesis by primary producers.

Select The Correct Statement About Photosynthesis By Primary Producers.

select the correct statement about photosynthesis by primary producers

Recall that the intensity of solar radiation reaching the earth's surface depends partly on location: the maximum energy intensity is received at the equator, and the intensity decreases as we move toward the poles. A Heat B Chemical C Light D None 32. In our example, the secondary production of the hare is the energy available to foxes who eat the hares for their needs. This implies loss, spoilage, or wastage of 0. There is not enough available energy to sustain a fifth level. Photosynthesis is critical for the existence of the vast majority of life on Earth. In contrast, roots bend away from the light as they grow.

In the next lecture we will examine how this energy moves through the rest of the ecosystem, providing fuel for life at higher trophic levels. C Global warming could have significant effects on United States agriculture. B tropical soil microorganisms do not break down organic matter as efficiently as temperate zone soil microorganisms do. D All of the given 11. Which of the following statements is correct? Thus over time it is the amount of new biomass that is produced, from whatever the standing stock of biomass might be, that is important for the next trophic level. Plants, coral, bacteria, and algae do this.

She can put her seeds in the refrigerator for a few months before planting. Plants can take in and use atmospheric nitrogen through their leaves. C as matter passes through ecosystems, some of it is lost to the environment. For the grassland shown in Figure 4-top, the bottom level would be quite large, due to the enormous number of small plants grasses. Just as we calculated the assimilation efficiency above, we can also calculate the net production efficiency for any organism. Let's use our knowledge of ecological energetics to examine this very important issue.

Nitrogen is cycled through living organisms. E phosphate is the limiting nutrient in these waters. The answer is any choice except glucose or oxygen. D the burning of larger amounts of wood and fossil fuels. Plants use nitrogen faster than it can be recycled back into the atmosphere. C Energy can be converted into matter; matter cannot be converted into energy.
