Solution

Pond ecosystem:

1. A pond or lake ecosystem contains biotic (living) plants, animals, and microorganisms, as well as abiotic (nonliving) physical and chemical interactions.
2. Lentic habitats are best represented by pond and lake ecosystems. From the Latin lentus, which means slow, lenttic refers to motionless or generally calm water.
3. Sunlight, nutrients, dissolved oxygen, temperature, pH, colour, and turbidity are examples of non-living or abiotic variables (i.e., water clarity).
4. These features, when combined, not only identify one pond from another, but also have a direct impact on the pond's output.

Test Description: Use your knowledge of Living Environment to answer all questions in the data set. You may need a calculator to answer some of the questions. Good Luck. Corresponding data sets: 56862, 56863, 56865, 56866

Instructions: Answer all questions to get your test result.

ADodder plants are consumers, transferring energy to other plants in the ecosystem. BDodder plants are producers, while the other plants that they attach to are consumers. CDodder plants are parasitic, relying on host organisms for resources. DDodder plants are decomposers, returning organic material back to the environment.

The Elements of Life

In biology, the elements of life are the essential building blocks that make up living things. They are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. The first four of these are the most important, as they are used to construct the molecules that are necessary to make up living cells. These elements form the basic building blocks of the major macromolecules of life, including carbohydrates, lipids, nucleic acids and proteins. Carbon is an important element for all living organisms, as it is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. Even the cell membranes are made of proteins. Carbon is also used to construct the energy-rich molecules adenosine triphosphate (ATP) and guanosine triphosphate (GTP). Hydrogen is used to construct the molecules water and organic compounds with carbon. Hydrogen is also used to construct ATP and GTP. Nitrogen is used to construct the basic building blocks of life, such as amino acids, nucleic acids, and proteins. It is also used to construct ATP and GTP. Oxygen is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids. It is also used to construct ATP and GTP. Phosphorus is used to construct the basic building blocks of life, such as carbohydrates, lipids, and nucleic acids.
