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.

Answers

Answer:

Cell-tissue-organ-organ system and finally an organism

Explanation:

The list that correctly shows the levels of organization in an organism is from left to right is  :

Cell --> Tissue ---> Organ ----> System -- > Organism

The cell is the basic unit of life, a group of similar cells performing similar functions make up a Tissue. While tissues perform more specialized functions when compared to cells.

Tissues make up an organ while a system like Digestive system , respiratory system, reproductive system are made up of a group of organs performing similar functions. The collection of all  systems make up an organism.

How is the periodic table of elements is organized?

The periodic table of elements also known as the periodic table is an organized alignment of the 118 elements known at present. The arrangement of chemical elements is done from left to right and from top to bottom on the basis of the enhancing atomic number, or the number of protons in the nucleus of an atom that usually coincides with the enhancing atomic mass.

On the periodic table, the horizontal rows are known as periods, in which each period number demonstrates the number of orbitals for the elements in that row.

Thus, the periodic table of elements is organized from left to right and from top to bottom based on the atomic number.

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.

Answers

Answer:

it is true

Explanation:

i took the quiz

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.

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.
