• Sunlight and water
• Sunlight, air, and water

• sunlight, soil, water and air

REMOVAL OF INVASIVE PLANT SPECIES

REDUCTION IN WATER UPTAKE BY ROOTS AFFECTS THE PLANT TO PRODUCE ITS ENERGY THROUGH PHOTOSYNTHESIS.

INVASIVE SPECIES PLANT REMOVAL

INVASIVE SPECIES- IS AN ORGANISM THAT IS NOT NATIVE (LOCAL) TO THE EOCOSYSTEM. LIKELY TO CAUSE HARM TO THE ENVIRONMENT AND ECOSYSTEM. NO ROOTS MEANS NO WATER ABSORPTION, WHICH MEANS THE PLANT CANNOT PHOTOSYNTHESIZE AND EVENTUALLY WILL DIE AND NOT REPRODUCE.
