Document Summary
Influences on light and temp variability in a region and plant adaptations to variability. To compare the photosynthetic strategies of c3, c4, and cam plants and how we can use those in sustainable agroecosystem design. Describe ways to modify temp, light, moisture, and wind. (microclimate of agroecosystem) Absorbs deep-blue and red light, so that the rest of the sunlight spectrum is being reflected, causing the plant to look green. Photosynthetically active radiation - range of light plants can absorb for photosynthesis (par) (400 - 760 mm) A lot of light gets reflected, some gets absorbed. Sunlight reaches different areas in different amounts (i. e. at equator direct sunlight, poles less sunlight) which determines their vegetation levels, animal life, microclimates, etc. Differs based on topography, latitude, seasonality, altitude, air quality. Light intensity - most plants need 6 hours as an average to grow properly. Light can be blocked by various things. Proximity of plants, tree cover, building cover, areas with.
