Answer:
Plants Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Explanation:
Fungi are eukaryotic organisms .they are feed on dead, decaying matter because they lack chloroplast. Most fungi are parasitic or symbiotic.
Fungi lacks root, stem and leaves. They however posses threadlike filaments called hyphae, which forms a larger mass called mycellium. Fungi reproduce asexually by spores. The classification of fungi are;
#zygomycetes, also called conjugation fungi .eg bread mold
#ascomycetes, also called sac fungi eg baker's yeast
#deuteromycota, also called imperfect fungi eg penicillium
#basidiomycetes .they are the commonly known mushrooms. They grow on wood and trees. Most of their species are edible. They are also called club fungi
Option C Habitat.... Polar bears are only found in the Arctic. The most important habitats for polar bears are the edges of pack ice where currents and wind interact, forming a continually melting and refreezing matrix of ice patches and leads (open spaces in the ocean between sea ice).
Thomas Malthus was economist who proposed that human populations grow faster than the resources they depend on which becomes limiting factor for them, causing the increase of populations but also increase of famine and diseases. As a consequence, the weakest members die. Darwin linked this with the “survival of the fittest" (naturals elections favors the best suited for reproduction and survival).
Georges Cuvier was anti-evolutionist and religious man, but he did have influence on Darwin theory of evolution (natural selection). He was against linear system of classification so, his believes that there is more than one lineage for species helped Darwin shaped his theory.
Charles Lyell geologists who believed that geologic processes that were at the beginning of time were the same ones that were happening at the current time (processes work the same way through time). He explained that slow changes built up over time, so Darwin linked that with the way that life on Earth changes. (small adaptations that accumulated over long periods of time change a species).
