This is a typical grassland food web. It is also a small picture of an important cycle on Earth: the carbon cycle. Describe how the carbon gets into this food web.a. Bacteria and fungi, the decomposers, recycle carbon from dead organisms.
b. Carbon is found in the grass and is passed from one level to the next in this food web.
c. All living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere.
d. Plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.

Answers

Answer 1

Answer: The correct answer is letter d. Plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar. In a typical grassland foodweb, carbon is used by plants (carbon dioxide) to create food for themselves.

Answer 2

Answer:

The correct answer would be option D.

In any food web, the inorganic carbon from the atmosphere is incorporated into the organic matter by the process of photosynthesis.

Autotrophs perform photosynthesis and fix carbon obtained from carbon dioxide into the glucose or organic matter with the help of chlorophyll and in the presence of sunlight.

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

Which of the following statements about angiosperm reproduction is true?a) Fruits reduce the success of dispersal because animals consume the seeds when eating the fruits.
b) There are a diverse array of flower shapes and colors, largely related to the mode of pollination.
c) The female gametophyte in angiosperms is larger than in gymnosperms.
d) It is less efficient than gymnosperm reproduction and requires more pollen.
e) Animal pollination is less efficient than wind pollination

Answers

The correct answer is: b) There are a diverse array of flower shapes and colors, largely related to the mode of pollination.

Angiosperms or flowering plants are plants with characteristic feature called flower. The main function of this plant structure is to ensure fertilization and development of fruit containing seeds. Flowers need to attract pollinators by their color, scent, and nectar (secreted in some part of the flower).

A pH of 2 is optimal for specific digestive enzymes found in a pig's stomach. If these enzymes are placed into a neutral substrate solution, what do you predict will be the outcome? A. The enzyme reaction time would decrease.
B. The enzyme reaction time would increase.
C. The enzyme reaction time would stay the same.
D. The optimal pH of the enzyme would change.

Answers

A. The enzyme reaction time would decrease as any pH level other than that of the optimal will lead to denaturing of the enzyme.

Almost all animals except _____ have either radial or bilateral symmetry

Answers

Sponges are the only animals which have asymmetrical body. Asymmetrical animals are animals which do not have pattern of symmetry. Sponges is an aggregation of different sponge cells. They form a colony with different shapes.

Ans.

Symmetry in animals can be defined as the balanced distribution of identical body shapes or parts within an organism's body. All animals, except sponges have either radical or asymmetry.

Sponges belong to phylum Porifera, which exhibit asymmetrical body plans. Their body shapes are adapted for maximum efficiency of water flow through their central cavity.

Thus, the correct word to be filled in the blank is 'sponges.'
