PLEASE HELP! I WILL GIVE BRAINLIEST. What 2 factors affect organisms and their habitats, and give examples of each

Grace [21]

Answer:

There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.

Explanation:

Biotic factors are interactions associated with living organisms. They can also influence the distribution of organisms in an ecosystem. grazing - too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity.

Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.

Jason has five equally massed lead fishing weights, each weighing 250 grams. What is the total mass of the five lead fishing wei

algol [13]

Answer:

1250 g=1.25 Kg

Explanation:

We are given that Jason has five fishes of equally massed lead fish weights.

Weigh of each fish =250 grams

We have to find the value of total mass of the five lead fishing weights

Total number of fishes=5

In order to find the total mass we will use unitary method

Total mass is obtained by multiplying the total number of fishes with weight of one fish

Total mass= $5\times 250$

Total mass of five fishes=1250 g

1 kg =1000g

Then 1250 g= $\frac{1250}{1000}=1.25 Kg$

Hence, total mass of five lead fishing weights=1250 g=1.25 Kg
