name two abiotic factors that contribute to the growth of phytoplankton?
Answers
Answer:
(autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize
Explanation:
The abiotic factors in the ocean help the ocean to 'work'. For example, phytoplankton (autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize. All of these factors are crucial to the primary producer!
Bacterial communities are an important part of biological diversity and biogeochemical cycling in aquatic ecosystems. In this study, the relationship amongst the phytoplankton species composition and abiotic environmental factors on seasonal changes in the community composition of free-living and attached bacteria in Lake Erhai were studied. Using Illumina high-throughput sequencing, we found that the impact of environmental factors on both the free-living and attached bacterial community composition was greater than that of the phytoplankton community, amongst which total phosphorus, Secchi disk, water temperature, dissolved oxygen and conductivity strongly influenced bacterial community composition. Microcystis blooms associated with subdominant Psephonema occurred during the summer and autumn, and Fragilaria, Melosira and Mougeotia were found at high densities in the other seasons. Only small numbers of algal species-specific bacteria, including Xanthomonadaceae (Proteobacteria) and Alcaligenaceae (Betaproteobacteria), were tightly coupled to Microcystis and Psephonema during Microcystis blooms. Redundancy analysis showed that although the composition of the bacterial communities was controlled by species composition mediated by changes in phytoplankton communities and abiotic environmental factors, the impact of the abiotic environment on both free-living and attached bacterial community compositions were greater than the impact of the phytoplankton community. These results suggest that the species composition of both free-living and attached bacterial communities are affected by abiotic environmental factors, even when under strong control by biotic factors, particularly dominant genera of Microcystis and Psephonema during algal blooms.
pls make me as brainlieast
The abiotic factors that could affect the growth of phytoplankton is sunlight and nutrients.
Phytoplankton are small photosynthetic organisms that are found in water. They are photosynthetic and occur close to the water surface due to their requirement for light.
Photosynthesis is the process by which green plants make their own food in the presence of sunlight and CO2.
Sunlight provides the energy required for photosynthesis while nutrients such as phosphates are required for phytoplankton growth.

Why is human population is growing so tremendously in terms of numbers of births and deaths?The human population is growing so tremendously in terms of numbers of births and deaths due to several factors, including:
Improved healthcare: Advances in medical technology and healthcare have led to a significant decrease in mortality rates, particularly in developing countries. This has resulted in more people surviving diseases and living longer lives.
Increased food production: Improved agricultural practices and technology have increased food production, resulting in more food being available to feed the growing population.
Higher fertility rates: Although fertility rates have declined in some countries, they remain high in many developing countries due to cultural and social factors, lack of access to family planning, and limited education and economic opportunities for women.
Urbanization: As people move from rural areas to cities, they tend to have smaller families, but the overall population continues to grow due to the influx of people into urban areas.
Overall, the growth of the human population is a complex issue that is influenced by a variety of social, economic, and environmental factors. It is important to address these factors to ensure that population growth is sustainable and does not result in negative consequences such as overconsumption of resources and environmental degradation.

Mitosis is a type of cell division which results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
What is diiferentiation?
Mitosis occurs in multicellular organism. Cellular differentiation is referred to as process by which a less specialized cell develop into a more specialized cell type.
Differentiation occurs many times during the development of a multicellular organism as the organism transform from a simple zygote to a complex system of tissues. Thus, mitosis and cell differentiation work together closely.
Differentiation is a usual process in adults and adult stem cells divide and develop into fully-differentiated daughter cells during tissue repair and during normal cell turnover.
Differentiation rapidly changes a cell's shape, size membrane potential, metabolic activity, and responsiveness to signals.

A biologist was studying a group of lions. Some lions had an extra fold in their nasal cavity called a turbinate. Exhaled air passes over the turbinate and water vapor in the air condenses and can be reabsorbed. Use the concept of natural selection to explain what you might expect to see if the climate changes. You can adjust the climate however you want. You must use the following terms in your answer:
Natural selection
Adaptation
Genetic variation
Heritable trait
I will mark brainliest whoever answers first!
Answers
Answer:
If the climate changes, the lions with the heritable trait of an extra fold in the nasal cavity (turbinate) would be better adapted to the new environment due to the water vapor reabsorbtion this turbinate allows. Thus, through natural selection, these lions would be more likely to survive in the new climate, and pass their genetic variation (which includes the turbinate) to their offspring. As a result, the presence of this heritable trait of the turbinate would be more common in the population of lions in the new climate.
Humans as a species, have many different kinds of skin colors that change across the globe. The amount of melanin produced by melanocytes in the skin determines skin color, which is affected by genetic and environmental factors. There is no generic trend in human skin color, but skin color tends to be darker in populations that live closer to the equator, where there is more intense sunlight and a higher need for UV radiation protection. Skin color is lighter in populations living farther away from the equator, where there is less intense sunlight and a greater need for the skin to create vitamin D.

Example of competition within a population:
Zebra mussels compete for food and space with other zebra mussels within their population in a freshwater ecosystem.
Example of competition among different species of a community:
Zebra mussels and quagga mussels compete for food and space in a freshwater ecosystem. Both species are filter feeders that compete for the same resources, which can lead to the displacement of one species by the other in some areas.
As the population increases, competition also increases.
As the number of individuals within a population increases, the demand for limited resources also increases, leading to increased competition between individuals for those resources. This can lead to decreased access to resources, decreased survival rates, and decreased reproductive success, which can ultimately affect the growth and stability of the population.
