Which of the Following Constitutes a Food Chain? Question: Which of the following constitutes a food chain? Answer Grass → Grasshopper → Frog → Snake → Hawk This sequence constitutes a food chain because each organism is eaten by the organism that follows it. It represents the transfer of food and energy through successive trophic levels. Explanation Grass – Producer (1st trophic level) Grasshopper – Primary consumer (2nd trophic level) Frog – Secondary consumer (3rd trophic level) Snake – Tertiary consumer (4th trophic level) Hawk – Higher-level consumer What Is a Food Chain? A food chain is a sequence of organisms in which each organism serves as food for the next organism. It shows the movement of food and the transfer of energy from one trophic level to another. A simple grazing food chain can be represented as: Producer → Herbivore → Carnivore → Higher-level consumer ...

The cell cycle is a series of events that prepare a cell for growth, DNA replication, and division. Among its stages, the S-phase, G2-phase, and M-phase are crucial for ensuring that the genetic material is accurately copied and equally distributed to daughter cells. Let’s break down each phase in detail. --- S-phase (Synthesis Phase) Definition: The S-phase is the part of interphase where DNA synthesis (replication) takes place. Key event: The amount of DNA doubles while the chromosome number remains the same. Example: If DNA content was 2C in G1, it becomes 4C after S-phase. However, if the chromosome number was 2n, it remains 2n. Other processes: In animal cells, DNA replication occurs in the nucleus. Centriole duplication takes place in the cytoplasm. Special feature: S-phase is also called the invisible phase because replicated chromosomes are not yet visible under the microscope. --- G2-phase (Gap 2 Phase) Definition: The G2-phase is the final stage of int...
