Chemosynthesis is one alternative to photosynthesis that primary producers have. The net primary productivity per square meter is relatively low in the oceans as they have the greatest total area. C) the increase in the average temperature of the whole planet The primary producers include plants, lichens, moss, bacteria and algae. Some chemical energy is not converted to new biomass as energy is transferred between trophic levels. C) only III Question 1. What is the reason for this seeming contradiction? You own 300 acres of patchy temperate forest. B) The total biomass of the fish is lower than that of the seals. Select the correct answer. C) fossilized plant and animal remains (coal, oil, and natural gas) A sample of wood contains $12.5 \%$ of its original carbon-14. A) industrial nitrogen fixation About how much of the chemical energy fixed by photosynthesis of the grass (100 percent) is available to the hawk? Found on soil and stones as well as some ferns and other plants, these poikilohydric plants are able to transition between active and resting phases depending on whether they are wet or dry. In order to complete the food chain, they also offer food for primary consumers, secondary consumers, and apex predators (also known as tertiary consumers). Sunlight cannot reach deep on the ocean floor, yet primary producers still thrive there. 5) Use the following figure to answer the question. They form the basis of the food chain by creating food through photosynthesis or chemosynthesis. Detritus can be consumed by which of the following primary decomposers? Primary producers are consumed by primary consumers (generally herbivores), which are then consumed by secondary consumers and so on. They are both autotrophic. sediments and sedimentary rocks 3. Explain. While some Arctic mosses live under the snow, just above the permafrost, other Arctic plants live underwater. 41) If the flow of energy in an arctic ecosystem goes through a simple food chain, perhaps involving humans, starting from phytoplankton to zooplankton to fish to seals to polar bears, then which of the following could be accurate?
