SAHARA DESERTBy Joel Kroeker

BIOME THAT I CHOSE:

The biome that I chose is a desert. But to be exact, I'm doing the Sahara desert, located in the northern part of Africa.

CLIMATE

The winters are considered cool for desert conditions, with an average temperature of 55° F (13° C).

The summers are very hot, with the highest ever recorded temperature at 13° F (58° C).

The sahara is one of the hottest places on earth

PHYSICAL FEATURES

(Soil)because of are carelessness, deserts are spreading over regions that have greenery, this is because of the misuse of are planet. However, this can be stopped by anti-desertification projects, and better land management. This will turn the deserts back, By making the soil stronger with the roots of plants embedded into them, and replenishing the soil with nutrient and minerals.

(Water)the rain in the Sahara desert is less then 10 inches a year, and there are very few lakes. Most of these lakes are only saltwater lakes, and people can not drink from them

Rivers once ran through the Sahara, because of the dried up lake beds.

BIOTIC/ABIOTIC THINGS IN THE DESERT

(Biotic) (Abiotic) Bush Sun Lizards Sky Trees Sand Camels Water

Skeletons (from animals)

Rocks

ORGANISMS FOUND IN DESERT:

Producer: Cactai, date palm Primary consumer: insects and reptiles

(e.g. kangaroo rat, etc) Secondary consumer: Lizards,

Mongoose, and snakes Decomposers: bacteria and fungi

SYMBIOTIC RELATIONSHIPS

Parasitism: fleas from desert rodents

Commensalism: lichen growing on tree bark

Mutualism: Insects, pollinating cacti. Animals, feeds on fruits on cacti and

disperses the seeds with the speces.

MY MADE—UP ORGANIZMS

Teeth: snake teeth. Vision: stereoscopic vision Senses: heat sensors. Thin body coverings Catching prey: mouth parts adapted to

grab, hold, bite, pierce, suck. Freezing into position/speed
