What are nutrients for? b) What is the difference between heterotrophic and autotrophic nutrition? c) What is the interaction process about? d) Explain 2 differences between asexual and sexual reproduction with your words. NUTRITION: When a living thing takes in essential nutrients from his or her Reproduction: When living things environment, these nutrients give him create members of their own species. or her energy and help with growth and development. Interaction: When a living thing detects -+ information in his or her environment and reacts to that information. NUTRITION Hetereotroph Organisms cannot make their own food. Then, they obtain it from the autotrophs. Autotroph Organisms making their own food. ASEXUAL REPRODUCTION SEXUAL REPRODUCTION Single individual is the sole parent. (ONLY). Two parents give rise to offspring. (descendants) Single parent passes on all its genes to its offspring Each person passes on half its genes to its offspring. Offspring are genetically identical to the parent. Offspring have a UNIQUE combination of genes inherited from both parents. Results in a CLONE, or genetically identical individual. Rearely, genetic differences occur as a result of mutation, a change in DNA. Results in greater genetic variation; offspring vary genetically from their siblings and parents.
