What may happen if the input of a mineral nutrient into an ecosystem is less than the output of that element from the ecosystem?
Expert Solution & Answer
Summary Introduction
To explain: The outcome when the input of a mineral nutrient into an ecosystem is less than the output of that element from the ecosystem.
Introduction: An ecosystem is a community of living things that interact with one another as well as with their environment. The living things are called biotic factors and the nonliving things are called abiotic factors. Both the biotic and abiotic factors are interdependent for nutrients and energy. Many external factors such as climate and soil, and internal factors such as decomposition and root competition can influence or control the ecosystem.
Explanation of Solution
An ecosystem is important for maintaining the various components together, that is, to maintain the balance between the living and nonliving things. The primary function of the ecosystem is the energy flow between the plants and the animal communities. Plants prepare food by photosynthesis, which requires the root to absorb the nutrients from the soil. The nutrients in the soil are enriched by the activity of decomposers. Thus, the nutrient supply for the plant, the producers, is supplied by the food chain. Herbivores eat plants, carnivores eat herbivores, and the decomposers feed on dead carnivores, and finally the nutrients are transferred again to the soil. When the output of a mineral is greater than the input of the mineral to the ecosystem, the production will be limited. This is because there are no enough mineral nutrients for production.

In a population of Jackalopes (pictured below), horn length will vary between
0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick
Jackalopes that have horn lengths around 1.75 feet to breed as this appears to
be the optimal length for battling other Jackalopes for food. After a round of
breeding, you measure the offsprings' mean horn length is 1.67. What is the
heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4
pts)?

There are many differences between DNA replication happening during mitosis in a Douglas fir tree
growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a
forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence
Repeat. Complete the following table that compares the two DNA replication events in terms of the
primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value
for the number of copies of the template DNA after one S phase in one cell and after the lab has
completed the PCR reaction.
