Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Scientific methodology includes the following: Objective observation: Measurement and data (possibly although not necessarily using mathematics as a tool) Evidence.

Macronutrients

Macronutrients, or “macros,” are carbohydrates, fats, and proteins. They are essential nutrients that provide energy and help keep people healthy. Some eating plans, like the ketogenic diet, require you to count macros once you start.

Carb:

Starches are present in plant-based foods such as potatoes, peas, corn, beans, rice, and other grain products.

Fats:

Avocados, Corn oil, Fatty fish, Flaxseed, Nuts, Olive oil, Peanut butter, Soybean oil, Sunflower oil.

Proteins:

Meat, poultry, and eggs: lean cuts of beef, lamb, goat, pork loin, skinless chicken and turkey, quail and duck

Forest Ecosystem

Forests consist not only of living (biotic) components like trees, animals, plants, and other living things but also of nonliving (abiotic) components such as soil, water, air, and landforms. All of these components together make up a forest ecosystem.

Desert

A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid.

Grassland

A grassland is an area where the vegetation is dominated by grasses. However, sedge and rush can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth.

Tundra Ecosystem

Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.

Marine Ecosystem

Marine ecosystems are aquatic environments with high levels of dissolved salt. These include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which has different physical and biological characteristics.

Freshwater

reshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content.
