1. Answer;
A. energy flows in one direction and nutrients recycle.
Explanation;
-The movements of energy and nutrients through living systems are different because the energy flows in one direction and nutrients recycle.
-Energy is transferred between organisms in one direction in a food chain, but that interconnected food chains make a food web.
-Most ecosystems get their energy from the Sun. Producers can use sunlight to make usable energy by converting it into chemical energy or food. Consumers get some of that energy when they eat producers, they pass some of the energy to other consumers when they are fed on.
2. Answer;
Nitrogen fixation.
Nitrogen fixation depends on bacteria.
Explanation;
Nitrogen fixation is the process by which nitrogen is taken from its stable gas form (N2) in air and then converted into other nitrogen compounds (such as ammonia, nitrate and nitrogen dioxide) useful for other chemical processes.
-The nitrogen fixing bacteria are microorganism capable of converting atmospheric nitrogen into forms usable by plants. They include the free-living bacteria, which includes cyanobacteria, azotobacter etc. and others such as mutualistic bacteria such as Rhizobium.
Fungi I hope this helps haha
Answer: The phenotype is a purple flower color.
Reasoning: If the dominant allele is present in the genotype, dominant traits will be expressed in the phenotype. Organisms that are heterozygous or homozygous dominant for a certain gene will always express that gene. Since this pea plant has the genotype Pp, the dominant allele (purple flower color) will be shown.
The energy flow within an ecosystem.
Animals can utilize both radiant and fixed energy. The fundamental unit of electromagnetic waves like light is radiant energy. Fixed energy is chemical potential stored in various organic materials that can be damaged to release their energy.
Autotrophs are organisms that can fix radiant energy and can synthesize organic compounds from inorganic materials. Heterotrophs are organisms that cannot receive energy from an abiotic source but rely on organic compounds produced by autotrophs that are rich in energy.

The oceanic crust is pulled under, which forms a subduction zone. Hope this helps.
