They help Us With Balance
Beneficial insects are any of a number of species of insects that perform valued services like pollination and pest control.
Beneficial Insects for Pest Control
This photo is from our watermelon raised bead, you see lady beetles mating, pre-pupa lady beetles, and an assassin bug.

Lady beetle eggs
What they eat
Aphids, they might actually be able to photosynthesize
We can Look Up Pests and Beneficial Insects By Crop
They are related to the lady beetle and are quite a bit smaller,
they mainly eat scale insects
LaceWing Life cycle
Antlions are the larval stage of lacewing like insects in the family Myrmeleontidae.
Incomplete Metamorphosis: When the nymph resembles the adult and there is no pupa stage

What is Soil Made of
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air. These percentages are only generalizations at best.

Stromatolites: are about 3.5 billion years old, calcareous mound built up of layers of lime-secreting cyanobacteria and trapped sediment, found in Precambrian rocks as the earliest known fossils, and still being formed in lagoons in Australasia.
Prokaryotes: about 3.5 billion years ago, a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.
Types of cells:
Prokaryotic cells have a cell wall, eukaryotic cells do not
Endosymbiotic Theory: the theory that free-living prokaryotic cells engulfed (ate) other free-living prokaryotic cells billions of years ago, forming eukaryotic organelles such as mitochondria and chloroplasts
Photosynthesis is the chemical reaction through which sunlight is transformed into sugar to use as:
1). usable energy to power cellular functions
2). stored energy that is kept in oils as potential energy and
3). some energy is used as building blocks for cell structures.
The molecule that cells use to power energy requiring functions is called ATP.
algae, a single celled organism that is not a plant but does photosynthesize.
It is a protist.
Algae can help us as food, fertilizer, and biofuel. it forms a big part of the base of the planetary food chain along with plankton.
Algae can be grown in open ponds and then the cells can be broken and separated into many components (pg 86). We can get oil for biodiesel, the carbohydrates can be fermented and used to produce ethanol which can be burned as fuel or electricity, the proteins can be used to feed people or livestock and the leftover biomass can be used as an organic fertilizer or burned for heat or electricity. It is good to consider our alternative, renewable energy sources.
Energy many be measured in joules, a joule is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre.
A megajoule is 1,000,000.00 joules
Producing one megajoule of Biodiesel removes 183 Kilograms of the greenhouse gas CO2 from the air while producing one megajoule of energy in Ethanol from corn adds 81-84 Kilograms of CO2 to the air.
We breathe out CO2 and plants use it to photosynthesize, a by product of photosynthesis is oxygen and we need a balance of chemicals in the air because breathing in too much CO2 is not good for us.
Here are some of the common symptoms of too much CO2, we call it respiratory acidosis:
We could die in an unbalanced environment.
