Q

what do they do to the chickens?

A
  • Keeping them cramped in a small space makes their energy form their food go to biosynthesis (growth) and not muscle contraction, or homeostasis (regulation of their bodies)
    • Give them hormones and selectively breeding them helps them to grow faster and bigger
      • Antibiotics also prevent them from getting sick before they do, less expensive then treating after.

Q

what happens in bio magnification?

A
  • Bugs eat the chemicals, primary consumer eats, then it carries on in the food chain
    • The top predators will then have so much of these toxins

the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.

Q

advantages of glasshouse farming?

A
  • Traps the heat
    • Lets light in
    • Control all factors of photosynthesis
      ○ Water, carbon dioxide, temperature, humidity
    • It lets more CO2 in than the natural environment
      Lets pests and animals
