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.

members of the animal and plant kingdoms are eukaryotic and multicellular. What is one way you can differentiate between a plant cell and an animal cell
Answer:
Plant cells have cell walls.
Explanation:
While both plant cells and animal cells have cell membranes, only plant cells have a cell wall, the hard outer shell of the cell.
Answer:
plant cells have cell walls and chlorophyll
Explanation:
animals do not have cell walls or chlorophyll so if the cell has either those two things, you know it's a plant cell.

What's wrong with this ecological pyramid?
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.

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

Please Help!!! Explain how the Periodic Table of elements is organized. What are the patterns? Trends?
Answer:
They are the alkali metals, alkaline earth metals, transition metals, other metals, metalloids, non-metals, halogens, noble gases and rare earth elements.
The chemical elements in the periodic table are organized from left to right and from top to bottom based on the atomic number.
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.

Which sentence describes what happens to plastic that absorbs energy from
sunlight?
A. It becomes brittle.
B. It shrinks.
C. It darkens in color.
D. It becomes stronger.
Answer: A
Explanation: just took the test :)
The plastic that absorbs energy from sunlight becomes shrink. The correct option is B.
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.
