Sign an experiment.
expeople1 [14]

The answers to the questions required for the design experiment above are :

  • If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases

  • If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal.

  • The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach.

  • The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low).

  • The Dependent variable : Number of shark attacks

  • The Independent variable : The different number of elephant seals found.

  • Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points.

  • John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.

The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.

The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.

The Experimental group are the portion of the subjects which are subjected to the treatment condition.

The Dependent variable is the measured variable is changes as the independent variables are tweaked.

Independent variable is the predictor variable, it causes a change in the output of the dependent variable.

In 3–5 sentences, compare and contrast the flow of matter and energy in each trophic level for land-based ecosystems and marine
Mnenie [13.5K]

Answer:

Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.

Explanation:

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.

Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
