B. The shells will enrich the compost as an additional organic supplement
C. The shells will have no effect for better or worse
D. The shells will kill the microfauna in the compost heap
Crushed eggshells, when added to a compost heap, serve as an organic supplement, enriching the compost by contributing key nutrients, particularly calcium, vital for plant health.
The addition of crushed eggshells to a compost heap will have a positive effect, making answer B the correct response. Crushed eggshells enrich the compost as they break down, adding valuable nutrients, specifically calcium, to the mix. Calcium is also an important nutrient for plant growth, so the shells can provide additional benefits when the compost is used in the garden. The eggshells are a form of organic supplement that enhance the quality of the compost, making it more effective when used as a soil additive. They will not harm the microfauna in the compost heap; in fact, they can provide grit for their digestive systems.

Answer:
A chicken
Explanation:
Answer:
Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.
Explanation:
The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.
In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.
To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.
b. biotic
Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
The term biotic factors has been defined as living factors present in the ecosystem. Biome is a separate biogeographical region that contains its own living and non-living factors along with a characteristic climate. The examples of biomes are: Tundra, Temperate, Desert, etc.
Changing a biotic or abiotic factor can affect each other or even the entire biome because these factor live in a state of dynamic equilibrium by being interdependent on each other. Therefore, if this equilibrium is disturbed then the survival of some living organism may be disturbed that can eventually lead to ecological succession.
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community.
Therefore, Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
