Ecosystem Portfolio:



  • Elephants
  • Lion
  • Cheetah
  • Leopard
  • Bison
  • Hippos
  • Nile Crocodile
  • Giraffe


  • Blue Grama
  • Buffalo Grass
  • Big Blue Stem
  • Switch Grass


  • Solar energy input is affected by season, cloud cover and changes in the Earth's orbit.
  • Light is important for plants for photosynthesis, for seed germination and for the behaviour of animals like reproduction time
  • Climate are rainfall, wind and high temperature
  • Topography are the surface of the land like height of mountains, the positions of the slopes that affect drainage and the behaviour of organism
  • Oxygen availability
  • Edaphic is connected with the soil like the pH of the soil, mineral salt of soil, the soil texture for example sandy soils are well drained and dry out quickly in hot weather but are never water logged in wet weather. Clay soils don't drain and restrain water in hot weather but are waterlogged in wet weather. The edaphic factors affect the plant distribution
  • Pollution in the air, water land
  • Catastrophes are like earth quakes that disrupt the conditions

Definition of Carrying Capacity

the number of people, other living organisms, or crops that a region can support without environmental degradation.

In order for a organism to survive it needs water, food, and shelter.

Population Over Time

Due to the human increase in population they have been taking resources from the safari and the giraffes are in a "silent extinction".

Definition and examples of Limiting factors

The environmental factor that tends to limit population size.

secretarybird  feeding on snakes

If the weather gets to cold all of the secretary birds prey will not be found and populations will drop.

Energy Roles

Level 1: The cuckoo flower or the scientific name   has blue-green colored stems with very narrow leaves. The flowers can be white to purple in color. This plant is sometimes called 'Lady's Smock' because the flowers resemble the shape of milkmaids smocks.

Level 2: Nigma walckenaeri spiders have a beautiful, bright green abdomen with a few white hairs giving them a shiny, or frosted appearance. The legs are a yellowish-green. Females have a green head (cephalothorax), while adult males have a brown head. Nigma walckenaeri spiders are usually referred to by their scientific name, but they are also known as the 'Ice Green Spiders' or 'Green Leaf Web Spiders'.

Level 3: The Pygmy Shrews or the scientific name  Sorex minutus are the smallest mammals found in the Safari. They are in fact smaller than some insects, and are sometimes found sleeping in the burrows of beetles. Superficially they look like mice but with a longer, pointed snout.

Food Webs/Food Chains

Food webs are more realistic than Food chains because, food webs contain more possibility's than a food chain

If i were to remove the leopard from this web then the population of the buffalo and the zebra would increase.

Energy pyramids

producers-1000 kcal

Primary consumer-100 kcal

Secondary consumer-10 kcal

Tertiary consumers-1 kcal

You need to use a pyramid shape rather than another because it shows that the lower you are in tropic levels the more there are. Producers are the largest level because they only transport 10% of their energy and they are making the energy so they start out with more.


the chemical equation for photosynthesis is CO2 + H2O -> C6H12O6 + O2

  1. A tropism is a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus.

You can find mostly Photo and Geo tropism here.

these tropisms help the plants to get the resources they need in order to keep living.


Decomposers help keep the environment healthy because they transform dead organisms into good soil for everything to use. A few types of decomposers in the safari are fungi,bacteria,and termites.

Good information for abiotic factors, but I would recommend making it a more simple, concise list. Looks good!

I like how organize your portfolio is

for carrying capacity i would separate the definition and what they need to survive
