B
The organisms will eventually die out since there is no plant source for the 1st level consumers.
C
The plant eaters of the ecosystem will just become meat eaters.
D
The number of meat-eating organisms will increase.
Explanation: 

Detailed explanation-1: -Drought Impacts on Ecosystems It encompasses and emphasizes the environmental consequences of drought, which include losses in plant growth; increases in fire and insect outbreaks; altered rates of carbon, nutrient, and water cycling; and local species extinctions.

Detailed explanation-2: -Drought stress reduces the plant growth by influencing various physiological as well as biochemical functions such as photosynthesis, chlorophyll synthesis, nutrient metabolism, ion uptake and translocation, respiration, and carbohydrates metabolism (Jaleel et al., 2008; Farooq et al., 2009b; Li et al., 2011).

Detailed explanation-3: -dries up, which adversely affects the growth and development of plants. The plants may die in such conditions. and the food supply for animals. Unavailability of food and drinking water may lead to starvation and death of the animals.

Detailed explanation-4: -Rainforest animals include mammals such as sloths, tapirs, jaguars, tigers, howler monkeys, spider monkeys and orangutans; reptiles such as caimans and the green anaconda; amphibians such as poison dart frogs and the red-eyed tree frog; and birds such as toucans, macaws and the harpy eagle.
