Answer:
D. A waxy coating on a plant
Explanation:
A cuticle can be described as a waxy covering which preserves or protects certain parts of plants like leaves, shoots etc. Lipid molecules which are saturated with waxes make up the cuticle. Cuticle majorly functions in stopping the evaporation of water from the cell's epidermal layers. All the species of plants possess this waxy coating of cuticle because it plays important role in stopping the loss of water from the cells.

Ecosystem is a community or group of living organisms that live in and interact with each other in a specific environment.
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
Amoeba are the consumers that surround, engulf, and ingest their food.
<h3><u>Explanation</u>:</h3>
Amoeba is a unicellular organism that belongs to the kingdom Protista. This organism are having eukaryotic cells without any cell walls. These organisms have each and every cellular organelle that are needed to perform metabolism.
Amoeba are consumer in mode of nutrition. Whenever they senses some food, they push a part of their cytoplasm packed in cell membrane towards the food to cover it. This process is called pseupodia.
This pseupodia engulfs the food and performs phagocytosis or pinocytosis. This food is covered in a cell membrane inside the cytoplasm which is called the food vacoule or endosome. This then fuses with a lysosome to digest and then the excretory product is let off by the secondary vacoule.
