Aim of the topic-- To demonstrate understanding of biological ideas relating to a mammal(s) as a consumer(s)
Life processes related to a mammal(s) as a consumer(s) will be selected from:
- Processing food
- physical digestion - teeth and stomach
- chemical digestion - enzyme action
- practical work related to digestive enzymes
- the effect of temp and pH on enzyme activity
- Absorption
- villus role and structure
- role of microvilli, capillary network and lacteal
- Assimilation
- Egestion
- Transport of products of digestion within the body (circulatory system)
- Respiration- process which allows cells to produce energy using glucose and oxygen
The Biological ideas relating to a mammal(s) as a consumer(s) will be selected from:
- Structural components involved with the life processes
- Functioning of the structural components-- compare digestive systems of herbivores, carnivores and omnivores
- The overall functioning of the life processes-- relate digestion, respiration, and circulation to each other and overall survival of the organism
