The first living cells to evolve on earth were single celled bacteria. These single celled organisms developed specialized structures to trap sunlight energy and to carry out photosynthesis e.g mitochondria, chloroplasts and lead to the development of multicellular organisms known as plants which are included in eukaryotes. All these changes have been found in fossil records of primitive organisms.
The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.
So, each sperm contains 50% of the father's genes and each egg contains 50% of the mother's genes. This makes gametes different from other cells in the body
Soils provide readily available nutrients to plants and animals by converting dead organic matter into various nutrient forms.
Soils can effectively remove impurities, kill disease agents, and degrade contaminants.
Soils maintain a net absorption of oxygen and methane, and undergo a net release of carbon dioxide and nitrous oxide.
Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.
Soils offer plants physical support, air, water, temperature moderation, nutrients, and protection from toxins.
If i’m correct i’m pretty sure the answer is D. only because grass is an autotroph that uses photosynthesis to transform sunlight into food and grass is a producer
