Answer:
The perch have 500 kcal of energy.
Explanation: Perch is a type of fish which feed on zooplankton, so it belongs to secondary consumer in the trophic levels. In aquatic ecosystem, plants are the producer which contains 50,000 kcal of energy. When these plants are eaten by primary consumer i. e. zooplankton, so only 10 % of energy is transferred about 5000 kcal. When zooplankton are eaten by perch fish, so 10 % energy is transferred again i. e. 500 kcal.
26% is taken up by ocean sediment. 26% taken by net terrestrial uptake and Human activities, especially conventional farming activities and burning fossil carbon as fuel, have disturbed the carbon cycle's balance, leading to more carbon dioxide being released into the atmosphere than is being taken up by plants
Females usually have smaller foot prints and they usually step in a pigeon toed manner with a smaller stride. However males, usually walks with a straightforward foot or quite tilted outwards. This is how to differentiate strides of men from women. Stride is defined as to walk long though extending steps. Women also walks gracefully they tend to walk femininely by swinging they hips and walking with short steps. In contrast, men's hip is quite stiffed when walking and takes longer steps when walking.
Cells use a complex assembly of molecules called a ribosome. This is how proteins are produced.
Plants are a renewable resource. Plants can be used repeatedly and easily, and naturally, replaced.
The energy yield from a gram of fatty acids is approximately 9 kcal (37 kJ)
When a plant is low on sugar, a cascade of molecular interactions degrades a protein called WRINKLED1 that turns on fatty acid synthesis is how plants produce oil- One cause is when you compare plants grown under strong nutrient deficiency with normal fertilized plants!
