We learn all about trees and their role in the ecosystem: why we need trees; how trees respond and adapt to their environment and process energy; oxygen production; fruit bearing trees; how tree seeds are spread; medicine from trees; parts of a tree; tree rings; deciduous and coniferous trees; tree species; how trees make and store energy through photosynthesis; types of forest ecosystems; forest layers; cooperative interaction among trees via fungal networks; impacts of deforestation; sustainability of forests; and the role of conservationists. Detailed graphics, diagrams and exciting video reinforce important concepts.
