A population's growth rate is limited by factors such as food, water, disease, and available habitat. The maximum population size an environment can sustainably support is called this.
carrying capacity
A satellite detects vegetation with high near-infrared reflectance and low red reflectance. This spectral pattern occurs because plant cells strongly reflect this wavelength while chlorophyll absorbs the red light.
near-infrared radiation
Why does increasing the concentration of dissolved salt in water generally increase its boiling point?
Dissolved particles cause boiling-point elevation
