Final answer:
Grass is found on all continents except Antarctica, which is primarily covered by ice with some areas having mosses and lichens.
Step-by-step explanation:
The question asks which feature is found on every continent except Antarctica. Considering the various biomes and geographical characteristics of each continent, the correct answer is d. grass. Grasslands, which include savannas and temperate grasslands, are present in diverse forms across Asia, Africa, North America, South America, Europe, and Australia. These areas are dominated by grasses, and such regions thrive in both tropical and temperate climates.
While Antarctica is largely covered by ice, it does have some non-ice areas with vegetation like mosses and lichens, but not grasses as we know them in other biomes. Therefore, grass is the feature found on all continents bar Antarctica.
