Perhaps the most significant factor that affects the biogeochemical cycles in the terms of human involvement is global warming, which disrupts natural cycles on various levels.
Answer:
mark me brainlist if i help:)
Explanation:
First of all, energy conservation plays an important role in saving non-renewable energy resources. Furthermore, non-renewable energy sources take many centuries to regenerate. Moreover, humans consume energy at a faster rate than it can be produced. Therefore, energy conservation would lead to the preservation of these precious non-renewable sources of energy.
Energy conservation will reduce the expenses related to fossil fuels. Fossil fuels are very expensive to mine. Therefore, consumers are required to pay higher prices for goods and services. Energy conservation would certainly reduce the amount of fossil fuel being mined. This, in turn, would reduce the costs of consumers.
Consequently, energy conservation would strengthen the economy as consumers will have more disposable income to spend on goods and services.
Energy conservation is good for scientific research. This is because; energy conservation gives researchers plenty of time to conduct researches.
Therefore, these researchers will have more time to come up with various energy solutions and alternatives. Humans must ensure to have fossil fuels as long as possible. This would give me enough time to finding practical solutions.
Answer:
<h2>Meiosis I</h2>
Explanation:
1. Meiosis (meiosis I and meiosis II) produce four daughter cells from a single cell, each daughter cell contains half the number of chromosomes as compared to parental cell.
2. Meiosis have two cycles , i) meiosis I and ii) meiosis II.
3. In meiosis I, chromosomes first go replication and become double. It is the first step (meiosis I) that generates genetic diversity. During prophase I of meiosis I, homologous chromosomes pair and form synapses, a special step of meiosis.
4. There is crossing over in meiosis I which produce genetic diversity.
5. The four cells produced from a single cell become genetically different due to crossing occur which occur in meiosis I.
Answer:
Arrows :
It shows how energy and nutrients are transferred from plants (producers) to herbivores and carnivores and through to decomposers. ... The arrows in the food chain below depict the direction in which energy and nutrients flow, i.e. the arrow always points from the eaten to the eater.
Greatest amount of energy transferred: Grass aka Autotrophs.
A sequence of living organisms which involves the transfer of food energy from producers, through a series of organisms with repeated eating and being eaten is called food chain. Each level or step in a food chain where the transfer of energy takes place is called trophic level. According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy. The flow of energy is unidirectional from producer to consumer level. The energy decreases at each trophic level of the food chain, as part of the energy is lost as heat and major part of the energy is liberated during respiration for use in various activities. Only 10% of the energy of previous trophic level is received by next trophic level, as proposed by 10 percent law of Lindeman.
