An energy pyramid illustrates that energy in the form of _____ is lost to the surroundings as it is passed from one organism to the next
The energy role of a grizzly bear is that of a(n)
_____ because it cannot make its own food
_____ cycle nutrients from dead organisms back to the soil, where it becomes available for plants
The _____ biome is characterized by its lack of trees, warm temperatures, and moderate rainfall
<u>Nitrogen-fixing bacteria</u> carry out the conversion of gaseous nitrogen to a biologically useful form of nitrogen
An energy pyramid illustrates that energy in the form of <u>heat</u> is lost to the surroundings as it is passed from one organism to the next
The energy role of a grizzly bear is that of a <u>consumer</u> because it cannot make its own food
<u>Decomposers</u> cycle nutrients from dead organisms back to the soil, where it becomes available for plants
The <u>Savanna</u> biome is characterized by its lack of trees, warm temperatures, and moderate rainfall
Explanation:
The nitrogen-fixing bacteria like Azotobacter which lives in symbiotic relationship in the rhizomes of leguminous plants. They convert inorganic atmospheric nitrogen gas through the action of its enzymes like nitrogenase to organic nitrogen in the form of ammonia, which is readily assimilated by the plants.
In an ecosystem, at each tropic level of an energy pyramid, only 10% of energy is utilized and transferred to the next higher tropic level whereas the majority of energy is dissipated as heat during various metabolic processes.
Decomposers also called saprophytes like earthworms, bacteria, fungi survives on dead and decayed remains of plants and animals and also on fertilizers, pesticides etc in the soil. They recycle the nutrients by breaking down the complex biomolecules into simpler forms and release back into the soil.
Grizzly bears being omnivores eat both plants and animals according to their availability. Hence they are both primary and secondary consumers.
Savanna is a grassland biome with a typical tropical wet and dry climate and receives moderate rainfall. Hence it cannot support trees but only have grasses.
Deoxyribonucleic acid is made up of two chains. A double helical structure is formed when two chains coil around each other.This double helical structure carry genetic information for the growth, reproduction, development and functioning of an organism.
The nucleic acid such as DNA and RNA are one of the major types of macromolecules which are necessary for all life forms.
The nucleotide is made up of one of four nitrogen containing nucleobases such as Adenine, Guanine, Cytosine and Thymine, Deoxyribose sugar and a Phosphate group.
European rabbits (Oryctolagus cuniculus) were introduced to Australia in the 18th century with the First Fleet and eventually became widespread. Such wild rabbit populations are a serious mammalian pest and invasive species in Australia causing millions of dollars of damage to crops.
<span>It is important to determine weather the heat is coming from the bottom of the phone or from a different area because if you feel the heat is being emitted from the bottom of the phone, this is indicative of a battery overheating. If heat comes from other areas, it often means the phone itself is overheating.</span>
The
correct answer is the gastrocnemius muscle.
<span>The
gastrocnemius muscle is a muscle located in the back part of the lower leg of
humans. The gastrocnemius together with the soleus muscle forms half of the
calf muscle with the function is plantar flexing the foot at the ankle joint
and flexing the leg at the knee joint.</span>
