• Abiotic
• A nonliving factor or element (e.g., light,
  water, heat, rock, energy, mineral).

3

  via "SWATS" (Soil, Water, Air, Temperature,
  Sunlight)

• Biotechnology
• The ways that humans apply biological concepts
  to produce products and provide services.

7
Biotechnology

• The wide concept of "biotech" or "biotechnology"
  encompasses a wide range of procedures (and
  history) for modifying living organisms according
  to human purposes, going back to domestication of
  animals, cultivation of plants, and
  "improvements" to these through breeding programs
  that employ artificial selection and
  hybridization. Modern usage also includes genetic
  engineering as well as cell and tissue culture
  technologies.
• Biotechnology dealing with medical and health
  care is termed as Red biotechnology. It is Green
  biotechnology, when it concerns about
  agricultural processes and White biotechnology
  when comes to industrial processes.

• Biotic

  by living organisms.

• From the greek word bios which means living

• Biological Diversity
• The variety and complexity of species present
  and interacting in an ecosystem and the relative
  abundance of each.

11
Biological Diversity

• This can also be called biodiversity.
• In practice, "biodiversity" suggests sustaining
  the diversity of species in each ecosystem as we
  plan human activities that affect the use of the
  land and natural resources. Why is biodiversity
  important?Everything that lives in an ecosystem
  is part of the web of life, including humans.
  Each species of vegetation and each creature has
  a place on the

• Closing the loop (recycling)
• A link in the circular chain of recycling events
  that promotes the use of products made with
  recycled materials.

13
Closing the loop

• This is the Chasing arrows symbol for recycling
• The design, created in 1970 by college sophomore
  Gary Anderson, actually symbolizes the closed
  loop system with each arrow depicting a step in
  the process.
• To get a better grasp on what it truly means to
  close the loop, lets take a closer look at the
  familiar chasing arrows and discover what they
  really mean.
• Collection The first step in the closed loop
  recycling system is collection. To put it simply,
  collection is when consumers toss recyclable
  products into their curbside bins or take them to
  a local drop-off center. Collected materials are
  processed at recycling facilities and prepared to
  be sold to manufacturers.
• Manufacturing Manufacturing recycled materials
  into new products is the second step of the
  closed loop system. Manufacturing plants create
  new products from recycled goods and ship them to
  retailers to be sold as new items.
• Purchasing The third and possibly most important
  step in the closed loop system is when you, the
  consumer, purchase products made from recycled
  materials. When consumers purchase
  recycled-content products, they essentially
  close the loop.

  needs or to use in the production of other goods
  for resale.

  matter, thereby making nutrients accessible to
