Drag each label to the correct location on the diagram. Each label can be used more than once, but not all labels will be used.
The diagram shows some of the steps in the flow of energy through an ecosystem. The arrows represent the transfer of energy. Label each
arrow with the type of energy being transferred.
chemical
electrical
thermal
radiant
nuclear
Answer/Explanation:
=> The first arrow linking the sun and the plants represents transfer of RADIANT energy. The sun through its sunlight radiation provides energy for autotrophs such as plants to manufacture their food.
=> The second arrow from plants to rodent represents transfer of CHEMICAL energy. The chemical energy that is manufactured and stored between the molecules of the plant as food, is transferred to rodents as primary consumers.
=> Third and fourth arrow from the rodent to owl, and from the rodent to the wolf both represents CHEMICAL energy transfer.
=> Fifth arrow from the wolf to the surroundings show heat loss during metabolic processes in the wolf's body which represents THERMAL energy transfer from the wolf to the environment.
=> The width arrow from the wolf to decomposers also show THERMAL energy transfer as the wolf dies and decay, Hera is released.
The arrows represent the transfer of energy which are described as follows:
1. Radiant energy
2. Chemical energy
3. Chemical energy
4. Chemical energy
5. Thermal energy
Radiant energy is transferred through the first arrow connecting the sun and the plants. Sunlight gives autotrophic organisms like plants the energy they need to produce food. The transfer of chemical energy from plants to rodents is shown by the second arrow. Rodents are the main consumers of chemical energy that is produced and stored as food between plant molecules.
The third and fourth arrows, from rodent to owl and from rodent to wolf, respectively, both indicate the transmission of chemical energy. The fifth arrow shows heat loss from the wolf's body during metabolic activities, indicating thermal energy transfer from the wolf to the surrounding environment.

A- Prophase
B- Cytokinesis
C-Interphase
D- Telophase
E- Metaphase
F-Anaphase
What is cell cycle?A cell's growth and division are accompanied by a sequence of processes known as a cell cycle. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
The chromosomes shorten and thicken during prophase. Chromosomes align in the center of the cell during metaphase. Chromatids split off at the centromere and migrate to opposite poles during anaphase. Telophase: Following the reorganization of nuclear envelopes around each cluster of chromosomes, two nuclei are created.
