A leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem
Flow of energy in the food chainMost of the energy that enters an ecosystem comes from solar radiation. The producing organisms that carry out photosynthesis absorb solar energy and fix it in chemical energy. When consumers feed on producers, part of that energy goes to these organisms, which, by serving as food for other living beings, also pass on part of their energy to them. This, therefore, flows, in a unidirectional direction, passing from a lower level to a higher one.
With this information, we can conclude that a leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem

Which is a tough and rigid layer that surrounds plant cells, as well as some algal and bacterial cells?
cell wall
centriole
nucleus
cell membrane
The tough and rigid layer that surrounds plant cells, as well as some algal and bacterial cells, is called the cell wall. Therefore, the correct statement is option A.
What are the functions of cell wall?The cell wall provides mechanical support to the cell, thereby, protecting it from damage caused by external factors. The cell wall consists of complex carbohydrates, such as cellulose, lignin, etc.
The cell membrane is selectively permeable, and the cell wall is porous allowing the passage of some molecules. The cell wall also helps in cell communication and signaling.
The cell wall determines the shape of the cell and helps in the regulation of growth and development. The thickness and composition of the cell wall change with respect to different environmental conditions and helps in the survival and function of many types of cells.
Therefore, the tough and rigid layer that surrounds plant cells is called the cell wall.

Which cell helps to move dust particles out of an organism? A ciliated cell B guard cell c muscle cell D red blood cell
Answer:
A) A ciliated cell
The cells that help to move dust particles out of an organism are known as red blood cells. Thus, the correct option for this question is D.
What is the function of Red-blood cells?The function of Red blood cells is determined by the fact that they carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
The amount of carbon dioxide that is accumulated in the body of an individual may be said to be a waste product because it is usually formed as the byproduct of several metabolic processes. Apart from carbon dioxide other waste products may also form in the body which is moved out of organisms with the help of red blood cells.
Therefore, the cells that help to move dust particles out of an organism are known as red blood cells. Thus, the correct option for this question is D.

Deforestation is the clearing of Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world's land area, but swaths the size of Panama are lost each and every year. Deforestation on such a large scale has a dramatic effect on the carbon cycle. Which of the following describes the effect large scale forest clearing will have on the carbon cycle.
Answer: B
Explanation:
the less trees the more carbon
Large-scale forest clearing, such as deforestation, has a significant impact on the carbon cycle. The carbon cycle is the process by which carbon moves between the atmosphere, land, and oceans and is an important part of regulating the Earth's climate.
What is deforestation?Forests are important for the carbon cycle because they absorb carbon dioxide from the atmosphere during photosynthesis and store it in their biomass and in the soil. When forests are cleared or burned, the carbon stored in the trees and soil is released into the atmosphere as carbon dioxide, contributing to greenhouse gas emissions and climate change. In addition, deforestation can disrupt the water cycle, leading to changes in rainfall patterns and soil moisture
Hence, large-scale forest clearing, such as deforestation, has a significant impact on the carbon cycle. The carbon cycle is the process by which carbon moves between the atmosphere, land, and oceans and is an important part of regulating the Earth's climate.

which sun is providing energy to this planet, and can the planet sustain life ?
Answer:
Without the sun's heat and light, life on Earth would not exist.
Explanation: The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis.
Answer:
no it cannot sustain itself without the sun.
Animals need the sun for vitimin D plants need it to photosynthesis and in the few cases that this isn't the case those plants are parasitic and still need photosynthesing plants to get energy from. So by removing the sun we lose plants that many herbovore animals rely on then they starve resulting in lose of food for carnivores so they starve aswell. And any life left after that would most likely freeze.
Some sphinx moth caterpillars are called tomato hornworms. These large caterpillars do a tremendous amount of damage to tomato plants. Which method of moth control would be most dangerous to the honeybee, which is needed for plant pollination?.
Answer:
Spraying plants with insecticides
The method of moth control would be most dangerous to the honeybee, which is needed for plant pollination is spraying plants with insecticides.
What is pollination ?Pollination is the transfer of pollen from a plant's anther to its stigma, allowing fertilization and seed production, most commonly by an animal or by wind.
Pollination is the transfer of pollen grains from stamens, the flower parts that produce them, to ovule-bearing organs or to the ovules (seed precursors). Pollen is simply caught in a drop of fluid secreted by the ovule in plants where the ovules are exposed, such as conifers and cycads.
Pollination is the process of moving pollen grains from the anther to the stigma of the same or different flowers. Self-pollination and cross-pollination are the two types of pollination.
