Best answer: Which role of protists has the most positive effect on maintaining the balance of an ecosystem?

Which role of protists has the most positive effect on maintaining the plant population in an ecosystem? Protists are a major food source for animals.

Why decomposing pioneer plants give way to larger more complex plants species such as hardwood trees?

During secondary succession, which of the these best describes why decomposing pioneer plants give way to larger, more complex plant species, such as hardwood trees? Increased amounts of soil from decomposing pioneer species allow plants with more extensive root systems to become established.

Which of the following best explains why cells that contain the same genetic material do not develop into the same types of cell?

The diagram shows how specialized body cells can develop. Which of the following best explains why cells that contain the same genetic material do not develop into the same type of cells? … Because random mutations can occur in the DNA of cells during early embryonic development.

Which role of fungi has the most effect on maintaining the plant population in an ecosystem?

Fungi are important decomposers in most ecosystems. Mycorrhizal fungi are essential for the growth of most plants.

Which of these best describes why decomposing pioneer plants give way to larger?

During secondary succession, which of these best describes why decomposing pioneer plants give way to larger, more complex plants species, such as hardwood trees? Increased amounts of sunlight are able to reach the ground while the pioneer species are decomposing.

How can most cells have the same genetic content and yet have different functions in the body?

Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on” (expressed). Thanks to gene regulation, each cell type in your body has a different set of active genes—despite the fact that almost all the cells of your body contain the exact same DNA.

What do you think causes the four cells to appear and function differently from one another?

Transcription factors can turn on at different times during cell differentiation. As cells mature and go through different stages (arrows), transcription factors (colored balls) can act on gene expression and change the cell in different ways. This change affects the next generation of cells derived from that cell.

Which statement best describes the role of the cell membrane in this model?

Answer: the cell membrane allows the solute to enter the cell which causes the cell to shrink. Explanation: cell membrane is semipermeable membrane, it selectively allows the movement of solute, water, salts, etc.

What is the effect of fungi on growth of plants?

Fungi participate in decomposition of organic matter and deliver nutrients for plant growth. Their role is very important in plant protection against pathogenic microorganisms as biological agents, which influences soil health (Frąc et al., 2015).

What is the role of fungi in agriculture?

Agricultural application of fungi. … Fungi produce a wide range of bioactive metabolites, which can improve plant growth [14]. In addition, fungi supply inorganic nutrients to plants, such as ammonium, nitrate, and phosphate [15] and they are used as biofertilizers.

What is the major role that fungi play in ecosystems?

Many act as decomposers, breaking down the dead bodies of plants and animals and recycling the nutrients they hold. … The fungal decay makes these nutrients and carbon dioxide available to green plants for photosynthesis, and it completes an important cycle of raw materials in the ecosystem.
