Unit 4 Chapter 15 - Forestry

Question 1

Albedo

Answer 1

The reflectiveness of a surface

Question 2

Biodiversity

Answer 2

A measure of the variety and abundance of species

Question 3

Canopy

Answer 3

The uppermost layer of vegetation in a forest

Question 4

Carbon sequestration

Answer 4

The process by which plants absorb carbon dioxide from the atmosphere and store the carbon in wood and other plant tissues

Question 5

Question 6

Climax community

Answer 6

The community of organisms at the end of ecological succession

Question 7

Community Forest

Answer 7

Question 11

Ecological succession

Answer 11

The sequence of events as a previously uncolonised area gradually changes to eventually develop into a climax community of organisms

Question 12

Evapotranspiration

Answer 12

Question 18

NPP

Answer 18

Net Primary Productivity: the energy captured by photosynthesis that is not used in respiration

Question 19

Pollarding

Answer 19

The process where trees are cut to 4 - 8ft above the ground every few years. The regrowth produces long narrow stems

Answer 21

Independent conservation organisation that manages the Rio Bravo Conservation and Management Area in Belize, Central America

Question 22

Stomata

Answer 22

The pore on a leaf through which gases are exchanged and transpiration water is lost

Layering, as seen with vegetation layers in forests

Question 24

Subsistence

Answer 24

Activities that support the people carrying it out, with no tradeable surplus
