Answer:

Explanation:

1.The monomers of carbohydrates are called monosaccharides. Examples are glucose and fructose. When we bond together 2 monosaccharides together by dehydration synthesis we get what’s called a disaccharide. Examples of disaccharides are sucrose and maltose. When many monosaccharides are connected by glycosidic linkages we call it a polysaccharide. The prefix poly refers to many. Examples of polysaccharides include starch in plants and amylose in animals.

an example of how water moves from
the biotic part to the abiotic part of an
ecosystem.

Answers

• Moving from abiotic to biotic: absorption by root hairs of plants
• Moving from biotic to abiotic: transpiration. Water evaporates from the leaves of plants.

One of the important examples of how water moves from the biotic part to the abiotic part of the ecosystem includes transpiration of water from the surface of the leaves of plant.

What is Transpiration?

Transpiration is the loss of water in the form of vapors from the surface of leaves of plant. Transpiration of water takes place from the stomata of plant cells.

Stomata are the specialized cells present on the surface of leaves which are covered by the guard cells that regulates the opening and closing of stomata and hence the movement of water from the leaf surface.

In transpiration, water from plant, a biotic part of ecosystem is lost in the form of vapors to the atmosphere, i.e., an abiotic component of ecosystem. The rate of transpiration is regulated by factors such as sunlight, concentration of ions like sodium and potassium, presence of starch.

What are harmful effects of plastic?

Endocrine disrupting substances (EDCs) are among them; they have been connected to a number of diseases such as infertility, obesity, diabetes, prostate cancer, and breast cancer.

In addition to these problems, chemicals have also been related to issues of neurodevelopment, growth, and reproduction.

Chlorinated plastic has the potential to leak dangerous chemicals into the soil around it. These chemicals can then seep into nearby water sources, including groundwater, and the ecosystem.

The species that consume the water may experience a variety of potentially dangerous impacts as a result.

The plastic is exposed to sunlight, which oxidises it and converts the polymers into oligomers, extremely soluble organic molecules.

Plastic breaks down into smaller molecules and absorbs UV radiation from the sun, thus how quickly it decomposes depends on how much of it is exposed to sunshine. This process is known as photodegradation in science.

Thus, the correct option is B.

Explain what happens at each of the following boundaries: ocean/ocean

convergent, divergent and transform plate boundaries.

Answers

Answer:

The particularly severe winter of 1777-1778 proved to be a great trial for the American army, and of the 11,000 soldiers stationed at Valley Forge, hundreds died from disease. However, the suffering troops were held together by loyalty to the Patriot cause and to General Washington, who stayed with his men.

Explanation:

Explanation:oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The material that is poured out are basaltic lave in nature. Basalt is denser and heavier than the granite that makes up continental plates.

Oceanic plates are much thinner than the continental plates. When an oceanic plate meets a continental plate at a convergent boundary the oceanic plate is forced under the continental plate and destroyed. The convergent boundaries between ocean and continental plates create subduction zones. The oceanic plate is pushed under the continental plate and melted. This melted material becomes magma that may reach the surface as volcanos, or solidify under the surface as granite.

Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates. The Granite and recycled material are much lighter than the heavy basalt layers of the ocean plates.

What's wrong with this ecological pyramid?

Answers

Answer:

The sun has an arrow leading to the decomposer, the sun should be at the bottom of the pyramid

Explanation:

The sun is the ultimate source of energy that provides energy to the producers. The producers use the light energy to synthesize the chemical compound. The energy from the producers is transferred to the primary consumers and their energy is transferred to the next levels. The sun cannot be decomposed by decomposer so the arrow from the sun leading towards the decomposer is not right.

Explanation:

False. Secondary succession does not happen after primary succession or independently of primary succession.

What is secondary succession?

Secondary succession is the process of ecological succession that occurs after a disturbance has disrupted an existing ecosystem, but left some soil and seed sources intact. Unlike primary succession, which starts with bare rock or soil with no living organisms, secondary succession begins in areas where there was already an established community of plants and animals.

Examples of disturbances that can lead to secondary succession include forest fires, landslides, and farming practices that disturb the soil. The process of secondary succession involves the gradual recolonization of the area by plants and animals, with different species replacing one another as the ecosystem gradually returns to a stable state.
