Question

1. infer: why does being alive mean carrying out all the life processes? 8. sequence: describe what happens to food after it is ingested by an animal. include a discussion of digestion, respiration, excretion, and transport in your description.

Explanation:

For question 7, being alive is defined by the performance of life - processes like growth, reproduction, metabolism etc. Without these, an organism is not considered alive. For question 8, after ingestion, food is broken down in the digestive system (digestion), nutrients are absorbed and transported to cells (transport), cells use oxygen to release energy from nutrients (respiration), and waste products are removed from the body (excretion).

Answer:

1. Life is characterized by life - processes. Without them, an organism is not alive.
2. After ingestion, food is digested in the digestive system. Nutrients are then absorbed and transported to cells. Cells use oxygen to release energy from nutrients through respiration. Waste products from these processes are excreted from the body.
