I believe the answer is a and d and b not 100% sure
The polarity of the water molecule helps it to cohere to nearby water molecules, forming a skin over it.
gamete: a mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
spore:a minutes typically one-felled, reproductive unit capable of giving rise to a new individual without sexual fusion, characteristic of lower plants, fungi, and protozoans.
algae: a simple, nonflowering, and typically aquatic plants of a large group that includes the seaweeds and many single-celled forms. algae contains chlorophyll but lack true stems, roots, leaves, and vascular tissue.
fungi:any group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.
lichen:a simple slow-growing plant that typically forms a low-crusty,leaflike, or branching growth on rocks, walls, and trees.
decomposer: an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
Thats odd my answer didnt get published stranged, anhow what I was saying is that due to the surface area and mass of the tree is has enough bouyency to stay afloat because of the surface tension on the water with the tree.
Answer: Protists
Explanation:
The protists are organisms which have characteristics similar to both plants and animals. There is huge diversity of protists on earth as they are single celled organisms and they increase in numbers by reproduction. They have a specialized cellular structure which includes organelles like nucleus, mitochondria, and others which are characteristic features of the eukaryotic organisms. They live in moist environment. They engulf their prey this way they are heterotrophic and they can also photosynthesize like plants.
