    That air obviously contained some oxygen and CO2.Plants
    need CO2 to live.They inhaled the CO2 and exhaled the
    Oxygen.With the Oxygen released by the plants,the ladybug survived and it exhaled CO2.The plants then again used the CO2 and exhaled Oxygen.In this way,it continues in a cycle.
    For making food,plants need 4 things: water,mineral,CO2
    and sunlight.Water and mineral is available in the wet soil.CO2 is available in the air,whereas,sunlight is also saying ‘hi’ there!So?Food prepared!
    Again,the main food of ladybug is small insect called ‘Aphid’,which sucks the juice of plants and live there.So, ladybug is getting enough food for her.This is how they both are surviving in the closed container.  less

Symbiosis means interaction between two dissimilar organism where both benefit from being with each other. When we are putting the ladybug and the plants inside the glass jar they are getting sealed from the rest of the world. The ladybug respires which releases carbon dioxide, which is taken up by the leaves of the plant. The leaves also get sufficient sunlight from the sun as the glass is transparent. And it also gets minerals from the charcoals in the soil ans as the soil was wet plants can absorb water from it too . The plants use this for photosynthesis and to produce oxygen and glucose. The glucose is used by the plants for food and the oxygen is used by the ladybug for respiration. The ladybug also feeds on the plants to survive. This is how the plant and the ladybug depends on each other to survive. This is known as symbiosis and this is why the plant and the ladybug both survived even if the container...    less

Plants produce their own oxygen during photosynthesis and by using that, bug is still alive. Bugs breath through openings in the thorax and abdomen called spiracles. For plants,those gravels will hold water and increase humidity. Charcoal increases the soils ability to hold onto plant nutrients and from wet soil plants get water. So using all of that in the process of photosynthesis,plant is growing and producing foods,oxygens and heat energy. This is how plants and the ladybug are still surviving in that closed container.  less

Plants have a process called photosynthesis which requires CO2 and sunlight to produce carbohydrates, water and oxygen for the plants' growth. Those plants need carbon dioxide to grow (plants absorb carbon dioxide through their stomata). For our container analogy, we can say that the plants inside the container are using photosynthesis to create their own food supply from sunlight and CO2. The gravel supplies nutrients such as nitrogen, magnesium and phosphorus which play important role in plant growth. Charcoal also acts like gravel by keeping up humidity levels for optimum growth conditions. The ladybug eats the plants, but both organisms benefit from receiving nutrients from each other.  less

    Few things ladybug needs to live-
    -Oxygen.
    -Food source.
    -Clean air that does not contain harmful gas like ammonia.
    -Suitable humidity
    -Available water source
    The jer fulfills the requirements like this-
    *Plants and algae give oxygen and get Co2 from ladybugs and other organisms.
    *Plants get energy from the sun and provide food for organisms. The energy stays almost the same as bacteria and protozoa decompose dead organisms and fallen leaves.
    *Bacteria and protozoa break down the waste and make ammonia into nitrate that plants can take. So the air stays clean.
    *Charcoal removes excess humidity.
    *Water evaporates but comes back to the system like rain.
    The jer completes the energy cycle, Co2 cycle, Oxygen Cycle, Hydrogen cycle, decomposition, and controls humidity and air quality. So, Ladybug and her friends can live happily by supporting each other.  less
