Strengths •Many Trees provide coverage for animals Weaknesses • Drastic changes in temperature due to seasons •Floods •Floods •Falling leaves enrich soil • Popular for hunting •The season Spring promotes new life •Popular for resources • Materials and food •Disease wipes out many plants •Plants are most likely to grow back again •A victim to deforestation •Animals are able to adapt Thank you for listening!
