Answer:The predicted population of brain coral in a reef covering 120m² is ; ≈ 40
First step : Calculate the value of the default population density
Population density = population size (dive 1) / total area
= 4 / 12 = 0.33
Total area ;
∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²
∴ Total area = 4 + 4 + 4 = 12m².
Final step : Determine the value of the predicted population of brain coral
Population density = ( predicted population ) / predicted area
0.33 = ( pp ) / 120m²
∴ Predicted population ( pp ) = 0.33 * 120
= 39.6 ≈ 40 brain corals
Hence we can conclude that the predicted population of brain coral is 40
Explanation:
The answer to this question is TRUE
Power is the rate (energy amount per time period) at which work is done or energy converted.
Answer:
A food chain showing how each living things which are present on the planet getting food. Plants are known as producer because they have ability to use a light energy comes from sun to produce, food. Animals are not able to make their food so, they are eating other animals, and plants. They are known as consumers.
In a food chain, energy is converted from one link to another link. In a food chain when a herbivore eats food it gets a fraction of energy from plant becomes new body mass. The left energy used by the herbivores for life processes such as reproduction, digestion, and movement or lost as a waste. When the carnivore eats herbivores it passes a small amount of energy to the carnivores, and same as herbivores some energy is used for life processes or some energy is wasted.
Because of the lots of energy is wasting at each link the actual amount of energy which is transferred decreases every time.
Answer:
A fossil is remain or impression of dead plants or animals which have lived thousands of years ago it can also be described as any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants
Types of Fossils. Fossilization can occur in many ways. Most fossils are preserved in one of five processes preserved remains, permineralization, molds and casts, replacement, and compression.
