Final answer:
Having fewer species of plants in the oil palm plantation would lead to fewer species of lizards because lizards rely on plants as a food source.
Step-by-step explanation:
Having fewer species of plants in the oil palm plantation would lead to fewer species of lizards because lizards rely on plants as a food source. When there are fewer types of plants available, there may not be enough food to support a diverse population of lizards. Additionally, fewer plant species can also lead to a decrease in insect populations, which are another important food source for lizards.
